Abstract

The present invention provides a dye-sensitized tandem solar cell that makes it possible to obtain a larger output. A dye-sensitized titanium dioxide electromotive body for a light incidence surface is arranged locally on a light incidence surface on the basis of the recent finding that locally forming a dye-sensitized titanium dioxide electromotive body that is arranged on the light incidence side of a dye-sensitized tandem solar cell makes it possible to obtain a larger short-circuit current than forming the dye-sensitized titanium dioxide electromotive body over the entire surface of the light incidence surface. A dye-sensitized tandem solar cell having a dye-sensitized titanium dioxide electromotive body that is formed locally on the light incidence surface thereof and that is arranged on the light incidence side makes it possible to obtain a larger short-circuit current than a dye-sensitized tandem solar cell having a dye-sensitized titanium dioxide electromotive body formed over the entire surface of the light incidence surface thereof.

色素増感タンデム２酸化ケイ素ソーラーセルDye-sensitized tandem silicon dioxide solar cell

　この出願の発明は、水晶等の２酸化ケイ素と色素増感２酸化チタンを組み合わせて起電する色素増感タンデム２酸化ケイ素ソーラーセルに係る。 The invention of this application relates to a dye-sensitized tandem silicon dioxide solar cell that generates electricity by combining silicon dioxide such as crystal and dye-sensitized titanium dioxide.

　シリコン等の半導体を用いた半導体ソーラーセルは変換効率が高い反面、高純度の材料を使用するため高価である。 A semiconductor solar cell using a semiconductor such as silicon has high conversion efficiency but is expensive because it uses a high-purity material.

　比較的安価なソーラーセルとして２酸化チタン（ＴｉＯ２）あるいは酸化亜鉛（ＺｎＯ）を用いるソーラーセルがある。
　２酸化チタンが起電に利用できる光は波長が３８０nm以下の紫外線のみであり、この波長領域の紫外線は太陽光中の４％に過ぎなく、太陽光の利用効率は最大でも４％、実際には１％がせいぜいであるため、太陽光の利用効率はきわめて低い。 As a relatively inexpensive solar cell, there is a solar cell using titanium dioxide (TiO 2 ) or zinc oxide (ZnO).
The light that can be used for the electromotive force of titanium dioxide is only ultraviolet light having a wavelength of 380 nm or less. The ultraviolet light in this wavelength region is only 4% of sunlight, and the utilization efficiency of sunlight is actually 4% at maximum. Is at most 1%, so the utilization efficiency of sunlight is very low.

　二酸化チタンソーラーセルが利用できる光の範囲を拡げ、太陽光の利用率を上げるために二酸化チタン起電体５にルテニウム錯体色素を付着させた色素増感型２酸化チタン起電体７は可視光の一部によっても起電できるため、色素増感型ソーラーセル（ＤＳＳＣ：Dye Sentitized Solar Cell）は可視光の一部によっても起電する。 The dye-sensitized titanium dioxide generator 7 in which the ruthenium complex dye is attached to the titanium dioxide generator 5 in order to expand the range of light that can be used by the titanium dioxide solar cell and increase the utilization rate of sunlight is visible light. Therefore, a dye-sensitized solar cell (DSSC: DyeitSentitized Solar Cell) also generates electricity by part of visible light.

It is a conceptual diagram of the silicon dioxide solar cell of a structure.

　この図において、２１及び２３は各々ＦＴＯ膜２２及びＦＴＯ膜２４を有するガラス基板であり、ＦＴＯ膜２２及びＦＴＯ膜２４は電荷取り出し電極として機能する。これらの構成は図１（ａ）に示した２酸化ケイ素ソーラーセルと同じ構造である。
　２７は酸化ケイ素焼成体からなる２酸化ケイ素起電体であり、電解液２８から分離されている。 In this figure, 21 and 23 are glass substrates each having an FTO film 22 and an FTO film 24, and the FTO film 22 and the FTO film 24 function as charge extraction electrodes. These structures are the same as those of the silicon dioxide solar cell shown in FIG.
