Title:
色素増感太陽電池素子
Document Type and Number:
Japanese Patent JP5377788
Kind Code:
B1
Abstract:
A dye-sensitized solar cell element includes at least one dye-sensitized solar cell, and the dye-sensitized solar cell includes a first electrode, a second electrode which faces the first electrode, and an oxide semiconductor layer which is provided on the first electrode. The oxide semiconductor layer includes a light absorbing layer which is provided on the first electrode and a reflecting layer as a layer which is in contact with a portion of a first surface of a side opposite to the first electrode among surfaces of the light absorbing layer and which is arranged at a position farthest from the first electrode. The first surface of the light absorbing layer includes a second surface which is in contact with the reflecting layer, and a surface area S 1 of the first surface and a surface area S 2 of the second surface satisfy the following formula: 0.7 ‰¤ S 2 / S 1 < 1 The reflecting layer is arranged in an inner side of the first surface of the light absorbing layer.
