DYE-SENSITIZED SOLAR CELL ELEMENT

摘要

A dye-sensitized solar cell (DSC) element includes at least one DSC, and the DSC includes a first electrode, a second electrode facing the first electrode, and an oxide semiconductor layer provided on the first electrode. The oxide semiconductor layer includes a light absorbing layer provided on the first electrode and a reflecting layer as a layer contacting a portion of a first surface of a side opposite to the first electrode among surfaces of the light absorbing layer and being arranged at a position farthest from the first electrode. The first surface of the light absorbing layer includes a second surface contacting the reflecting layer, and a surface area S1 of the first surface and a surface area S2 of the second surface satisfy the following formula:;0.7≦S2/S1<1;The reflecting layer is arranged in an inner side of the first surface of the light absorbing layer.
