[Prior Art 3] Dye-sensitized solar This battery is a photoelectrochemical solar cell using an oxidized dye molecule capable of absorbing visible light rays to generate an electron-hole pair, and an oxide composed of titanium oxide for transferring electrons generated Semiconductor electrode. In the conventional tantalum solar cell, the solar absorption program and the electromotive force generation program by the separation of the electron-hole pair occur simultaneously in the germanium semiconductor, and in another aspect, in the dye-sensitized solar cell, the solar absorption program And the charge transfer procedure is performed separately. In particular, the dye-sensitized solar cell towel 'dye absorbs solar energy' and the semiconductor transfers charge. Compared with the existing Shishi solar cell, the dye-sensitized solar cell has a low manufacturing cost, which is environmentally friendly and can be manufactured. However, because of its low energy conversion efficiency, it has practical limitations. ... Therefore 'in order to increase the energy conversion efficiency of dye-sensitized solar cells' may require an increase in the absorption of sunlight and an increase in the amount of dye absorption, thus increasing the amount of stimulated electricity plus electrons generated by the recombination of holes in 200929581, or prevention of electrons. - The exhaustion of the child and so on. Therefore, in order to increase the amount of dye absorption per unit area, a method of preparing oxide semiconductor particles having a size of several nanometers, and a method of increasing the reflectance of a platinum electrode to increase the absorption of sunlight are currently being developed. A method of sizing a semiconductor oxide light diffuser, and the like.

In addition, the long-term operation of the dye-sensitized solar cell can cause the absorbed dye to be separated from the oxide semiconductor particles, thereby reducing energy efficiency. Therefore, compared with germanium solar cells, since the deterioration of the dye-sensitized solar cell shortens the life of the dye-sensitized solar cell, and it negatively affects its long-term stability and practicability, there is an urgent need to develop and solve the above problems and achieve A dye-sensitized solar cell that has the same lifetime as the Shi Xi solar cell or a longer life than the Shi Xi solar cell 4 200929581.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail. 5 m 10 15 Ο The present invention relates to a method for extending the life of a dye-sensitized solar cell. More specifically, the present invention relates to a method for extending the life of a dye-sensitized solar flb battery (1 〇〇), the battery comprising: a negative electrode (10) comprising semiconductor particles, and a surface facing the negative electrode (1〇) a positive electrode (2〇), a dye absorbed into the negative electrode (10), an electrolyte (30) filled between the negative electrode (10) and the positive electrode (2), and a frame (40) surrounding the negative electrode (20) The method comprises the steps of: (1) supplementing the electrolyte with an insufficient component of the electrolyte or (ii) exchanging the electrolyte. The life of the dye-sensitized solar cell is determined by the decrease in energy efficiency due to the volatilization of volatile substances contained in the electrolyte. Therefore, in the case where this problem occurs, the insufficient component of the electrolyte component, preferably a volatile component, can be supplemented to improve the electrolyte characteristics, thereby prolonging the life of the solar cell. In addition to supplementing the insufficient components of the electrolyte, the electrolyte can be supplemented. More specifically, the insufficient portion of the electrolyte previously filled in the solar cell can be filled by replenishing a new electrolyte. An embodiment of the structure of this type of dye-sensitized solar cell is shown in Fig. 1. In addition, the existing electrolyte may be exchanged with a new electrolyte, or an existing electrolyte may be extracted and an insufficient component may be added thereto, impurities may be removed therefrom, or an insufficient amount may be supplemented to replace the existing electrolyte, so that the solar cell may display a similar The energy efficiency of the new solar cell, thereby extending the life of the solar 20 200929581 battery. An embodiment of the structure of this type of dye-sensitized solar cell is shown in Fig. 2. The exchange of electrolytes can be carried out by the following method. First, the electrolyte can be exchanged by: (a) discharging the electrolyte filled between the 5 pole and the positive electrode, (b) injecting the dye into the solar cell, and then optionally circulating the dye to cause absorption, and The dye is then discharged and (4) an electrolyte is injected between the positive electrode and the positive electrode in the solar cell. Furthermore, the step of drying the inside of the solar cell may be further included between the steps (a) and (8) or between the steps (9) and (:, because the deterioration of the cation battery is caused by deterioration of the electrolyte and the dye Desorption occurs, © In order to prevent such phenomena, a dye absorption step may be further included. More specifically, the previously filled electrolyte is discharged from the existing solar cell, and if necessary, an inert gas or scrambled gas is required (if necessary) a heated ambient gas can be used to circulate the electrolyte remaining in the battery so that the drying process is carried out, and then the dye can be used alone (the dye can be used alone, and the dispersion of the dye in the solvent can be used to For the smooth supply of dye) into the solar cell 'and maintain - for a period of time or continuous cycle (cycle is more than because it can increase the absorption efficiency), so that the dye can be absorbed into the particles of the negative electrode (mainly titanium oxide) In the nanoparticle), and subsequently, by 20 to remove the remaining dye, and then, if necessary, optionally and repeatedly (alternately Perform the drying procedure explained above (for initiating dye adsorption) or the usual cleaning procedure (for removing residual dyes), and then new electrolytes (including electrolytes and new electrolytes prepared by adding insufficient components to existing electrolytes) Injecting into the battery, thereby removing the previously desorbed dye of 200929581, supplementing the insufficient absorbing dye by the above absorption program, and filling the battery with a new electrolyte containing the added insufficient component, thereby improving the energy of the solar cell Efficiency' thus extends the life of the dye-sensitized solar cell. 5 ❹ 10 15 Lu 20 In addition, the process can be simplified as follows: (a,) discharging the electrolyte filled between the negative electrode and the positive electrode, and (b,) injecting a dye containing The electrolyte, and then optionally circulated, thereby extending the life of the solar cell. More specifically, discharging the previously filled electrolyte and injecting the electrolyte containing the dye into the battery by mixing the dye With new electrolytes (including by adding insufficient ingredients to existing electrolytes) The electrolyte and the new electrolyte are prepared so that the dye absorption process and the filling process of the new electrolyte can be performed by a process. The process is essentially a two-step process involving the discharge of the electrolyte and the injection of the electrolyte containing the dye. During solar cell operation, the absorption of the dye is continuously performed, and thus the two-off procedure is not required, and the injection of the new electrolyte is completed in the above procedure. Alternatively, the process is performed as follows: discharging the previously filled electrolyte, and Injecting the electrolyte of the L material into the battery 'The dye-containing electrolyte is prepared by the material and the new electrolyte (including adding the insufficient component to the existing electrolyte = prepared electrolyte and new electrolyte), and maintaining the same time ^ The application of the dye induces the absorption of the dye, and is as dense as the current state. Here, the absorption of the soap is preferably a teacher; the cycle (""-η) increases the absorption efficiency because of its increased blowing rate. The above process in the step (b,) m comprises (iv) a dye-containing electrolysis between the negative electrode and the positive electrode in the solar cell and injecting an electrolyte containing no dye. In other words, the new electrolyte can be filled in the battery to increase the energy efficiency of the electrolyte. Preferably, the above procedure may further comprise the step of drying the interior of the solar cell between the steps (a,) and (b,) or between the steps (10) and (6). Thereby, residual substances can be removed or absorption efficiency can be increased. Further, the washing step may be further included in conjunction with the drying step, or the drying step and the cleaning step may be alternately performed. The present invention also provides a life extension device for performing the above life extension method. The device comprises: a dye-sensitized solar cell (100) comprising: a negative electrode (10) comprising semiconductor particles, and a positive electrode facing the negative electrode (10) 20) a dye absorbed into the negative electrode (10), an electrolyte (30) filled between the negative electrode ((9) and the positive electrode (4), and a frame (4〇) surrounding the same, and having a portion connected to the filling electrolyte (30) The inlet section (5〇) and the outlet section (6〇); a mechanism (2〇〇) for supplying electrolyte or dye to the inlet σ section (5G); 15 and connecting to the outlet section (60) The mechanism for recovering electrolytes or dyes (300). One example of this device is shown in Figure 3. More specifically, for the exchange of electrolytes, the device @& is equipped with solar energy An electrolyte recovery mechanism (recovery tank) for the outlet section of the battery, for the discharge of the electrolyte previously filled in the solar cell 20, and the apparatus is provided with an electrolyte supply mechanism, which is an electrolyte storage tank, a pump for supplying electrolyte from the storage tank And connect the pump to too A supply line of an inlet section of a battery for supplying a new electrolyte.
