Dye-sensitized solar cell

Abstract

A main object of the present invention is to provide a dye-sensitized solar cell capable of improving photoelectric conversion efficiency, which is obtained at low costs, and a dye-sensitized solar cell module using the solar cell. The present invention solves the problem by providing a dye-sensitized solar cell comprising: an oxide semiconductor electrode substrate having: a first electrode base material provided with a function as an electrode, and a porous layer formed on the first electrode base material and containing a dye-sensitizer-supported fine particle of a metal oxide semiconductor; and a counter substrate having a second electrode base material provided with a function as an electrode; and a polymer electrolyte layer formed between the oxide semiconductor electrode substrate and the counter substrate so as to contact with the porous layer, in which the oxide semiconductor electrode substrate and the counter substrate are disposed such that the porous layer and the second electrode base material are opposed to each other, wherein at least one of the first electrode base material and the second electrode base material is a base material having transparency and wherein the polymer electrolyte layer contains a transparent fine particle, a polymeric compound and a redox pair.
