Description

Solar cell composite glass plate

The present invention relates to a solar cell composite glass plate which transmits light required for visible light or the like and controls the transmission amount of unnecessary light such as ultraviolet light or infrared light.

Glass plates are widely used for lighting in buildings, lighting, temperature adjustment in greenhouses for plant cultivation, dimming of lighting for stage, studio, and photography, and ensuring the visibility of transportation devices such as automobiles.

The glass plates used in these devices simultaneously transmit visible light, ultraviolet light, and infrared light.

Although the amount of energy in the ultraviolet light containing sunlight is less than 6%, since the wavelength is short and the energy is large, there is a chemical change in the object irradiated by the ultraviolet light, thereby causing adverse effects such as discoloration or embrittlement. .

Infrared light accounts for 48% of the amount of energy in sunlight, and the temperature of the irradiated object rises due to the infrared ray.

In a building or a greenhouse having a glazing for lighting, in order to prevent an increase in temperature due to incident infrared light, it is necessary to ventilate and refrigerate, and energy such as electric power is required.

The stage, the studio, and the photographic lighting fixture use a tungsten bulb or a halogen bulb to ensure color rendering, and radiate a large amount of infrared rays to excessively heat the irradiated body including the person.

Used in windows for lighting in a variety of conveyors, including automobiles. glass. There is a case where the ultraviolet light incident from the glass window causes inflammation to the skin of the occupant such as the driver, and the infrared light causes the temperature inside the vehicle to rise.

In this way, even if ultraviolet light and infrared light are not required, it will transmit the glass plate together with the visible light required, causing a chemical change or an undesired rise in temperature of the object to be irradiated.

In order to avoid the transmission of unwanted ultraviolet light, several conventionally adopted configurations are disclosed.

Fig. 1(a) shows a glass plate disclosed in Japanese Laid-Open Patent Publication No. Hei 9-235141 and Japanese Patent Application Laid-Open No. Hei No. No. Hei 10-17336, which reduces the transmission of ultraviolet rays by mixing the glass itself with the ultraviolet absorbing material. the amount.

The one shown in Fig. 1 (b) is disclosed in Japanese Laid-Open Patent Publication No. Hei 9-110474, the Japanese Patent Publication No. Hei 9-227168, the Japanese Patent Publication No. Hei 10-194780, and the Japanese Patent Publication No. 2002-523267. The glass plate is coated with an ultraviolet light absorbing material 3 on the surface of the glass plate 2 to absorb ultraviolet light.

Figure 1 (c) shows a material coated on the surface of the glass plate different from the refractive index of the glass plate, so that the incident ultraviolet light and the reflected ultraviolet light reflected by the glass surface interfere with each other to reflect the ultraviolet light and attenuate the transmitted light. .

In this case, more material 5, 6 or a laminate having a different refractive index is laminated on the glass plate 4 in order to more reliably interfere.

As a configuration for avoiding the transmission of unnecessary ultraviolet light, the absorption by the coated material shown in Fig. 1(b) is disclosed in Japanese Patent Laid-Open No. Hei 10-194780.

Providing a film having a thickness of one-fourth of the wavelength of light to be interrupted by the glass plate, and transmitting by interference of light reflected at the interfaces on both sides of the film The light reflection is disclosed in Japanese Laid-Open Patent Publication No. 2002-348145, and the visible light transmittance is 82% and the infrared light reflectance is obtained by a laminated structure of titanium oxide and yttrium oxide formed by a sputtering method. A 50% glass plate is shown in "http://www.aist.go.jp/aist_j/press_release/pr2007/pr20070625/pr20070625.html".

In the case of using materials that absorb ultraviolet light, the material will be ultraviolet light. Chemical changes occur and life is shortened. Further, in the case of absorbing ultraviolet light or in the case of reflecting ultraviolet light, as long as it is in the case of a coating material, the material may be thinned due to friction during cleaning or the like, or the life may be changed due to peeling. short.

Since the material that absorbs ultraviolet light is usually colored, the amount of visible light is also reduced, which not only visually darkens, but also stains on the weathered side, and the effect is attenuated.

As a method to avoid the transmission of unwanted infrared light, Infrared light is absorbed by a component contained in the glass plate itself or by coating an infrared light absorbing material on the surface of the glass plate, or a refractive index and a glass plate are coated on the surface of the glass plate as disclosed in Japanese Laid-Open Patent Publication No. 2002-345145 Different materials reduce incident infrared light by interfering with incident infrared light and reflected infrared light reflected from the surface of the glass plate.

In the case of using materials that absorb infrared light, due to the absorption of infrared light The material absorbs more visible light with a shorter wavelength than infrared light, thus reducing the amount of visible light transmission and making it darker visually. Further, in the case of absorbing ultraviolet light or in the case of reflecting ultraviolet light, as long as it is in the case of a coating material, the material may be thinned due to friction during cleaning or the like, or the life may be changed due to peeling. short.

Further, dirt is deposited on the surface of the weathering side, and the effect is attenuated.

Moreover, since ultraviolet light and infrared light are electromagnetic waves, they have energy and benefit. A material that absorbs in the case of absorption, and an external object that is irradiated with reflected light in the case of reflection, receives energy and rises in temperature, or may cause some chemical change, and not only because it absorbs visible light at the same time, thereby making visible light The amount of transmission is reduced and darkened.

In the case of utilizing the interference generated by the film, due to the film according to the film The wavelength of light that is thick and whose transmission is suppressed is limited, so that the suppression effect can be exerted only for light of a specific wavelength.

Forming an n-type zinc oxide semiconductor and a p-type copper on a glass substrate A pn junction made of an aluminum semiconductor, a transparent window glass system that is electrified by ultraviolet light of 350 nm to 450 nm blue green light is disclosed in "http://www.aist.go.jp/aist_j/press_release /pr2003/pr20030625/pr20030625.html".

According to the description, the visible light transmittance of the window glass is 50%, and the infrared light is transparent. The incident rate is 70% or more, which is visually dark due to less transmitted visible light, and is hotter due to more transmitted infrared light.

It is also disclosed in the document that a sheet-shaped semiconductor is provided on a glass plate, The infrared light is reflected by the vibration of the plasma.

However, the glass plate discards the infrared rays to the incident side by reflection. Therefore, the incident side becomes a high temperature and becomes a cause of thermal pollution.

In "Sharp Technical Journal" No. 77, 81-82 In the "Lighting Solar Cell Module" (published in August 2000), a solar cell module in which a single crystal, a polycrystalline, or a thin film solar cell of 125 mm square is sandwiched by a composite glass plate is disclosed and lighted.

Since the solar cell module uses a crystal or thin film solar cell, This visible light has a very small amount of transmission, and it is extremely non-use as a lighting unit in window glass or the like. full.

[Titanium dioxide solar cells and cerium oxide solar cells]

Prior to describing the form for carrying out the invention, the prior art titanium dioxide solar cell and cerium oxide solar cell will be described with reference to FIG.

[Titanium Dioxide Solar Cell]

(a) The basic structure of the titanium dioxide solar cell is shown.

In the figure, 11 and 13 are glass substrates each having an FTO (Fluorine-doped Tin Oxide) layer 12 and an FTO layer 14, and the FTO layers 12 and 14 function as charge extraction electrodes.

15 series porous titanium oxide sintered body, 16 series electrolyte. The electrolyte 16 is usually used as an iodine-based electrolyte in which iodine is dissolved in an aqueous solution of potassium iodide.

The electrons are excited from the porous titania sintered body 15 by the ultraviolet light incident on the FTO transparent conductive film 12 on the glass substrate 11, and the excited electrons are taken out from the FTO transparent conductive layer 12 to the outside through the load 17. The FTO transparent conductive film 14 is returned to the porous titania sintered body 15 via the electrolyte 16.

Titanium dioxide solar cells are powered by ultraviolet light, but the amount of ultraviolet light contained in sunlight is only 6%, so the comprehensive utilization of sunlight is not high.

In order to expand the range of light available for titanium dioxide solar cells and to improve the utilization of sunlight, there is a so-called dye-sensitized solar cell in which a ruthenium complex pigment is attached to a titanium oxide sintered body (DSSC: Dye Sentitized Solar Cell). In addition, since the dye-sensitized solar cell can be electrified by one of visible light, the utilization efficiency of sunlight is increased and attention is paid.

In the dye-sensitized titanium dioxide solar cell system, a pigment such as a ruthenium complex dye is adsorbed on the vacant surface of the porous titanium oxide sintered body 15 as a ruthenium complex pigment When the visible light is absorbed, the erbium complex pigment is excited from the state of the electron substrate, and electrons are injected into the porous titania sintered body 15 to electrify by visible light.

The electrons injected into the porous titania sintered body 15 are transparent from FTO The conductive material 12 is taken out to the outside, and is returned from the FTO transparent conductive film 14 through the electrolyte 16 through the load 17 to return the erbium complex dye.

[cerium oxide solar cell]

(b) The cerium oxide solar cell 20 invented by the inventors of the present invention disclosed in the International Patent Publication No. WO2011/049156.

In the figure, 21 and 23 are glass substrates each having an FTO layer 22 and an FTO layer 24, and the FTO layer 22 and the FTO layer 24 function as charge extraction electrodes.

25 series cerium oxide calcined body. Further, the 26-series electrolyte is usually used as an iodine-based electrolyte obtained by dissolving iodine in an aqueous solution of potassium iodide.

A semiconductor layer 25 such as zinc oxide (ZnO) is formed as a counter electrode in the FTO layer on the light incident side.

A platinum film 28 is formed in the light incident side FTO layer 24.

As the semiconductor layer 25 to be the counter electrode, titanium oxide (TiO ₂ ), copper oxide (CuO), magnesium oxide (MgO), barium titanate (SrTiO ₃ ), carbon nitride, graphene, or the like may be used. .

Between the semiconductor layer 25 and the platinum film 28, a photovoltaic material 26 is sealed with a thickness of 0.15 to 0.20 mm. The photovoltaic material 26 is obtained by mixing a glass powder containing hydrofluoric acid-treated SiO ₂ and an electrolyte.

The electrolyte used was obtained by adding LiI 0.1 mol, I ₂ 0.05 mol, 4-tris-butylpyridine 0.5 mol, and tetrabutylammonium iodide 0.5 mol to an acetonitrile solvent.

The cerium oxide solar cell 20 is light-derived from the glass substrate 21 or 23 Which side of the incident is electrified.

The inventors of the present invention are directed to a titanium dioxide solar cell and a cerium oxide solar The battery can be further studied and the following new insights are obtained.

[Titanium Dioxide Solar Cell]

When the titanium dioxide solar cell is electrified by ultraviolet light, only when a load is connected between the FTO transparent conductive layer 12 and the FTO transparent conductive layer 14, no electrification occurs when the load is not connected.

The titanium dioxide solar cell consumes incident ultraviolet light when it is electrically connected to a load, but does not operate as a solar cell when no load is connected and does not perform electrification, and therefore does not consume incident ultraviolet light.

From another point of view, when the titanium dioxide solar cell is connected with a load, The amount of transmitted light is reduced by the incident ultraviolet light, and the amount of transmitted light is not reduced when the load is not connected.

It means that by connecting the load to the titanium dioxide solar cell, Or by changing the load, the amount of transmission of ultraviolet light can be changed.

Further, by using a titanium dioxide solar cell for a lighting portion such as a window glass and changing the load, a window glass which can control the transmission amount of ultraviolet light can be obtained.

As a counter electrode, titanium dioxide solar cells are often used such as carbon or metal. The non-translucent material of the board may be the same as the transparent conductor on the light incident side, so that a translucent solar cell can be constructed.

In the dye-sensitized titanium dioxide solar cell, the wave of the light of the electrification The length varies depending on the sensitizing dye used. Therefore, the wavelength of light that can control the amount of transmitted light by the sensitizing dye can be selected.

[cerium oxide solar cell]

The inventors have found that a cerium oxide solar cell can be electrified by infrared light.

The measurement was made using a glass plate having a thickness of 4 mm formed with an FTO film. The light transmittance of the cerium oxide solar cell and the two FTO glasses constituting the both sides of the cerium oxide solar cell.

The cerium oxide solar cell almost 100% blocks the light in the wavelength region below 470 nm. In contrast, the FTO glass almost 100% blocks the light in the wavelength region below 289 nm, but the wavelength region from 289 nm to 470 nm is obtained. The light is transmitted by more than 65%.

Further, the cerium oxide solar cell blocks 84.7% of the light at a wavelength of 800 nm, whereas the FTO glass transmits 84.3% of the light.

Measuring pairs of cerium oxide solar cell composite glass sheets as heat rays The infrared ray heat ray blocking effect. The measuring system uses a glass plate for windows of the present invention having different thicknesses, and a glass plate for use as a comparative example, and a glass plate for windows is mounted on one side of a rectangular box-shaped white box in order to eliminate the influence of heat on the inside. The infrared light is irradiated onto the glazing panel to measure the temperature inside and outside the box. The glass sheet for the window of the invention of the present application is connected to an external load and the external load is changed.

In the case of using a universal glass plate, the temperature difference between the inside and outside of the box is not full. In contrast, in the case of the glass plate of the invention of the present application, a temperature difference of 15 to 20 ° C is exhibited.

Cerium dioxide solar cell composite glass plate will be produced when the load is large A temperature difference of up to 3 °C. It is shown that the infrared ray is blocked by causing the cerium oxide solar cell composite glass plate to be electrified by infrared rays.

The cerium oxide solar cell is powered by infrared light only in When a load is connected between the FTO transparent conductive layer 22 and the FTO transparent conductive layer 24, it is not connected. No power is applied during load.

In other words, the cerium oxide solar cell consumes incident infrared light to electrify when it is connected to a load, but does not consume incident infrared light when the load is not connected.

From another point of view, when the solar dioxide solar cell is connected to a load, The incident infrared light is consumed to reduce the amount of transmitted infrared light, and the amount of transmitted infrared light incident when the load is not connected is not reduced.

It means that by connecting the load to the solar cell of the cerium oxide, Or by changing the load, the amount of transmission of infrared light can be changed.

Further, when a cerium oxide solar cell is used for a lighting portion such as a window glass and the load is changed, a window glass which can control the amount of transmission of infrared light can be obtained.

As a relative electrode, the cerium oxide solar cell may not use, for example, carbon or gold. A non-translucent material of the board is used, and a transparent conductor similar to the light incident side is used, thereby constituting a light-transmitting solar cell.

[Unwanted light transmission control composite glass plate]

The titanium dioxide solar cell is electrified by ultraviolet light having a wavelength of 380 nm or less, and the cerium oxide solar cell is electrified by light from visible light to infrared light.

From another point of view, the transmittance of ultraviolet light having a wavelength of 380 nm or less can be controlled by forming the titanium dioxide solar cell into a light transmissive type, and the self-visible light region can be controlled by forming the ceria solar cell into a light transmissive type. The amount of light transmitted to the infrared range.

Based on this finding, the lighting unit such as the window glass is configured as a light transmitting type titanium dioxide solar battery.

Thereby, the transmissive ultraviolet light control composite glass plate can be obtained, and the transmission infrared light control can be obtained by forming the lighting portion such as the window glass as a light transmitting type ceria solar cell. Glass plate.

The control of the amount of transmitted light is performed by controlling the load connected to the solar cells constituting the composite glass plate.

In this case, if the titanium dioxide solar cell is used as a dye-sensitized type and the dye to be used is selected, the amount of unnecessary light transmitted by the corresponding wavelength can be controlled.

Even if it is configured as a cerium oxide solar cell, the infrared light does not operate in a state in which the load is not connected, that is, in a state where the external circuit is not closed, so that the incident infrared light is not in the cerium oxide solar cell. It is consumed, and even if it is absorbed in the cerium oxide solar cell, most of it will be emitted to the outside by reflection or transmission.

In other words, the erbium dioxide solar cell to which the load is connected by closing the circuit is electrified by infrared light, and the incident infrared light is not emitted to the outside.

Further, the erbium dioxide solar cell which is not connected to the load by the open circuit does not electrify by infrared light, and emits infrared light to the outside.

That is, the erbium dioxide solar cell, which is closed by the load circuit and is activated by infrared light, blocks or attenuates the infrared light.

Further, the cerium oxide solar cell in which the load circuit is open without being activated by infrared light does not block or attenuate the infrared light.

This means that the cerium oxide solar cell in which the extraction electrode is formed on the glass substrate can control the amount of transmitted infrared light by the connection of the load circuit.

In the present application, in the present application, the composite glass plate is formed by setting the titanium dioxide solar cell and/or the ceria solar cell into a light transmissive type, and the load connected to the solar cell is changed to change the amount of transmitted light.

Further, in the present application, an invention of a composite glass panel is provided, which The transmitted light can be selected, in other words, the amount of light that is not transmitted and the amount of transmitted light can be selected, and from another angle, the amount of light that is not transmitted can be controlled.

In view of such circumstances, the invention of the composite glass sheet of the transmission amount of light which is not required for the control of the present application is completed.

Hereinafter, the embodiment will be described using the drawings.

[Example 1]

[Transmissive ultraviolet light blocking composite glass plate]

The conceptual construction and function of a composite glass sheet that controls the transmission of ultraviolet light will be described with reference to FIG. The composite glass plate directly uses the ultraviolet solar cell of the prior art shown in FIG. 2(a) as a composite glass plate, and adds a load and a switch for connecting the load.

In the figure, 11 and 13 are glass substrates each having an FTO layer 12 and an FTO layer 14, a 15-series porous titanium oxide (TiO ₂ ) sintered body, a 16-series electrolyte, a 17-series load, and an 18-series switch.

The FTO layers 12 and 14 each function as a charge extraction transparent electrode, and the load 17 is connected via the switch 18.

As the transparent electrode, FTO doped with fluorine in the oxide of tin is used. However, although the FTO is low in cost but has a large resistance value, it is necessary to make the film thickness large, and as a result, the transmittance of light is lowered.

When ITO (Indium Tin Oxides) formed of 5% of an indium oxide and a low-cost tin oxide of 5% is used as a transparent electrode, it is expensive because of using indium as a rare earth element. Since the film thickness can be made thin, the light transmittance is slightly improved as compared with the case of using FTO.

Further, as the transparent electrode, a carbon-based material such as a carbon nanotube or graphene, or a conductive PET (polyethylene terephthalate) film or the like can be used.

The 15-series porous titanium oxide sintered body is formed of an anatase type having a wide specific surface area and formed of ultrafine particles having a diameter of 10 to 30 nm.

There are several types of porous titanium oxide sintered bodies, and other types of sintered bodies can also be used.

Further, when a small amount of titanium dioxide particles or rutile particles having a size slightly larger than the ultrafine particles having a diameter of 10 to 30 nm is mixed, the characteristics are improved by the sealing effect by local light scattering.

The titanium dioxide solar cell can also be used as a dye-sensitized type, and the representative dye used is a ruthenium complex dye, and other porphyrin or cyanine, C60 derivative or BTS (styryl benzothiazolium propylsulfonate, styrylbenzene) can be used. Plant-derived pigments such as thiazolyl propyl sulfonate, cinnabar or betel nut can be selectively used for electrification light by using pigments having different electrification properties.

As the electrolyte 16, various electrolytes such as a cation such as a lithium ion or an anion such as a chloride ion are used as a supporting electrolyte, and a redox pair such as an iodine-iodine compound or a bromine-bromine compound is used as a redox pair present in the electrolyte.

The following electrolyte was used in this Example 1.

0.4 mol of 1-ethyl-3-methylimidazolium iodide, 0.4 mol of tetrabutylammonium iodide, 0.2 mol of 4-tributylpyridine, 0.1 mol of guanidinium isothiocyanate as solvent And the preparer.

When the concentration of the halogen molecule is 0.0004 mol/L or less, the electrolyte is substantially colorless and transparent in the visible light region.

In addition, the following electrolytes can also be used.

A lithium iodide (LiI) 0.5 mol, a metal iodine (I ₂ ) 0.05 mol, and a polyethylene glycol having a molecular weight of 220 were prepared as a solvent.

Further, the following electrolytes can also be used.

A tackifier is added to dissolve zinc iodide (LiI) 0.5 mol and metal iodine (I ₂ ) 0.05 mol in methoxypropionitrile, and 4-tributylpyridine is added to increase the open circuit electromotive force and the filling factor.

The electrolyte having the highest value is as follows.

The following components are mixed in a predetermined ratio: LiI and I ₂ , 3-methoxypropionitrile as a solvent, and 1-propyl-2,3 dimethyl iodide as a room temperature molten salt which lowers the viscosity and smoothes the diffusion of ions. Imidazolium, and 4-tris-butylpyridine which prevents reverse current and increases the open circuit voltage.

In the case of a dye-sensitized titanium dioxide solar cell, if the solvent is made into a water system, the life of the dye is shortened. Therefore, an organic solvent of a mixed solution of 20 vol% of acetonitrile and 80 vol% of ethyl acetate is used.

Further, in the case where the composite glass plate does not need to be colorless and transparent, a colored electrolyte such as an iodine-based electrolytic solution may be used.

As the colorless electrolyte, an organic acid such as acetic acid or citric acid can also be used.

The function of the composite glass sheet 10 will be described.

In the composite glass sheet 10 shown in (a), the switch 18 to which the load 17 is connected is opened.

Therefore, the composite glass plate 10 does not operate as a titanium dioxide solar cell, and does not electrify even when ultraviolet light is incident, and the ultraviolet light which is incident on the composite glass plate 10 together with visible light and infrared light maintains the original together with visible light and infrared light. Transmitted and emitted.

In the composite glass sheet 10 shown in (b), the switch 18 to which the load 17 is connected is closed.

Therefore, when the ultraviolet light is incident, the composite glass plate 10 operates as a titanium dioxide solar cell to perform electrification, and the ultraviolet light incident on the composite glass plate 10 together with visible light and infrared light is attenuated and emitted for electrification, visible light and infrared light. The light remains in its original state, Exit.

That is, when the composite glass plate 10 having the titanium dioxide solar cell structure is connected to a load, it functions as an ultraviolet light to block the composite glass plate.

The confirmation of the attenuation of the transmitted ultraviolet light is to intercept the composite glass plate 10 by injecting ultraviolet light having a wavelength of 352 mm from invisible light into the ultraviolet light, and irradiate the emitted ultraviolet light to the fluorescent tube to observe the change of the emitted fluorescent light. And proceed.

As a result, when the ultraviolet light blocking glass 10 was connected to the load and the electrification was performed, it was confirmed that the fluorescent tube was darkened and the transmitted ultraviolet light was attenuated.

Since titanium dioxide does not absorb visible light, all visible light can be transmitted, and the porous titanium oxide sintered body which is a sintered body of titanium dioxide can also remove reflection due to scattering and transmit visible light. Therefore, since the sintered titanium oxide is transparent in the case of a small thickness, the field of view can be secured, and thus it can be used as a usual window glass.

On the other hand, although the sintered titanium oxide has a large thickness, it hinders the horizon and becomes opaque. However, in this case, the lighting function can be ensured and the frosted glass can be used as a barrier to the field of view.

[Embodiment 2]

[Transmissive infrared light blocking composite glass plate]

The conceptual construction and function of the composite glass sheet 20 for blocking the transmission of infrared light will be described with reference to FIG.

The structure of the composite glass plate is not the infrared light solar cell of the prior art shown in Fig. 2(b), but the structure of the composite glass plate which blocks the transmission of ultraviolet light as shown in Fig. 2(a).

In the figure, 21 and 23 are glass substrates each having an FTO layer 22 and an FTO layer 24, a 25-series porous cerium oxide (SiO ₂ ) fired body, a 26-series electrolyte, a 17-series load, and an 18-series switch.

The FTO layers 22 and 24 each function as a charge extraction transparent electrode, and the load 17 is connected via the switch 18.

As the transparent electrode material, FTO doped with fluorine in the oxide of tin is used, but a carbon-based material such as ITO, a carbon nanotube, or graphene, or a conductive PET film can be used. The case of the titanium dioxide solar cell is common, and therefore further explanation is omitted.

The 25 series is a cerium oxide particle calcined body obtained by treating a synthetic crystal having a particle diameter of 500 nm or less with hydrofluoric acid, and mixing and calcining the platinum powder with ethanol.

The diameter of the cerium oxide particles is not limited to particles of 500 nm or less, and may be used even at a diameter of about 0.2 mm.

As the electrolyte 26, various electrolytes such as a cation such as a lithium ion or an anion such as a chloride ion are used as a supporting electrolyte, and a redox pair such as an iodine-iodine compound or a bromine-bromine compound is used as a redox pair present in the electrolyte.

The following electrolyte was used in this Example 2.

0.4 mol of 1-ethyl-3-methylimidazolium iodide, 0.4 mol of tetrabutylammonium iodide, 0.2 mol of 4-tributylpyridine, 0.1 mol of guanidinium isothiocyanate as solvent And the preparer.

When the concentration of the halogen molecule is 0.0004 mol/L or less, the electrolyte is substantially colorless and transparent in the visible light region.

Since the electrolyte which can be used in common is the same as the case of the titanium dioxide solar cell of Example 1, further explanation is omitted.

Further, when it is not required to be colorless and transparent, a colored electrolyte such as an iodine-based electrolyte having a reduced concentration may be used.

As the colorless electrolyte, acetic acid, citric acid or the like can also be used.

The function of the composite glass sheet 20 will be described.

The switch 18 to which the load 17 is connected is opened in the composite glass sheet 20 shown in (a).

Therefore, the composite glass plate 20 does not operate as a ceria solar cell, and does not electrify even when infrared light is incident, and the infrared light and the ultraviolet light and the visible light which are incident on the composite glass plate 20 together with the ultraviolet light and the visible light are common. Keep the original state transmitted and emitted.

The switch 18 to which the load 17 is connected is closed in the composite glass sheet 20 shown in (b).

Therefore, when the infrared light is incident, the composite glass plate 20 operates as a cerium oxide solar cell to perform electrification, and the infrared light incident on the composite glass plate 20 together with the ultraviolet light and the visible light is attenuated and emitted for electrification. Ultraviolet light and visible light remain in their original state and transmit and exit.

That is, when the composite glass plate 20 having the ceria solar cell structure is connected to a load, it functions as infrared light to block the composite glass plate.

The confirmation of the transmission infrared light attenuation was performed by injecting near-infrared light having a wavelength of 800 nm into the composite glass plate 20, and observing the temperature of the emitted light.

As a result, the transmission amount of the incident infrared light was 15.3%, that is, the attenuation amount was 84.7%.

The calcined body of cerium oxide removes reflection caused by scattering and transmits visible light. Therefore, the calcined cerium oxide is transparent in the case where the thickness is small, and the field of view is secured, so that it can be used as a usual glazing.

On the other hand, calcined cerium oxide becomes opaque due to scattering of incident light when the thickness is large, which hinders the horizon, but in this case, the lighting function can be ensured and the frosted glass is used as a barrier to the field of view.
