DYE-SENSITIZED SOLAR CELL AND METHOD FOR MANUFACTURING SAME

摘要

To provide a dye-sensitized solar cell capable of significantly improving power extraction efficiency, and a manufacturing method of the dye-sensitized solar cell. The dye-sensitized solar cell includes a substrate, a porous semiconductor layer adsorbing a dye, a conductive metal layer, and a conductive substrate. The conductive metal layer 16 is a current collector provided on the side of the porous semiconductor layer, the side being opposite to the side on which the substrate is arranged. The conductive metal layer 16 is configured by a conductive metal section 17 made of a mesh member, and a coating section 19 formed on the conductive metal section 17. The coating section 19 is configured by an inner layer 19a and an outer layer 19b, and has a graded composition structure in which the degree of oxidization of the coating section is increased from the side of the conductive metal section 17 toward the side of the porous semiconductor layer 14. Thereby, the coating section 19 has a graded composition structure in which the thermal expansion coefficient of the coating section is reduced from the side of the conductive metal section 17 toward the side of the porous semiconductor layer 14.
