NOVELTY - A dye-sensitized solar cell comprises an electrode base material (10), a porous semiconductor layer (20), an electrolyte layer (30) and a counter electrode (40) which is provided by facing the porous semiconductor layer and electrode base material. The electrolyte layer has a primary electrolyte layer (31) having permeated pore internal portion, and secondary electrolyte layer (32). The concentration of oxidation reduction pair contained in the primary electrolyte layer is less than the concentration of oxidation reduction pair contained in the secondary electrolyte layer.    USE - Dye-sensitized solar cell is used for solar cell module (claimed).    ADVANTAGE - The dye-sensitized solar cell has high photoelectric conversion efficiency. The recombination reaction of electric charge and oxidation reduction pair is inhibited. The transfer of electric charges is preformed smoothly by maintaining high oxidation reduction pair concentration between the gaps.    DETAILED DESCRIPTION - A dye-sensitized solar cell comprises an electrode base material, a porous semiconductor layer, an electrolyte layer and a counter electrode which is provided by facing the porous semiconductor layer and electrode base material. The porous semiconductor layer is formed on the electrode base material and has pore surface supporting a sensitizing dye.
