DYE-SENSITIZED SOLAR CELL AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2010/023860

A1

Provided are a dye-sensitized solar cell wherein power extraction efficiency is greatly improved, and a method for manufacturing the dye-sensitized solar cell. The dye-sensitized solar cell is provided with a substrate, a porous semiconductor layer having a dye adsorbed therein, a conductive metal layer, and a conductive substrate.  The conductive metal layer (16) is a power collecting section arranged on the porous semiconductor layer side opposite to the side where the substrate is arranged.  The conductive metal layer (16) is composed of the conductive metal section (17) composed of a mesh member, and a covered section (19) covered with the conductive metal section (17).  The covered section (19) is composed of an inner layer (19a) and an outer layer (19b), and has a gradient composition structure wherein oxidation degree increases toward the porous semiconductor layer (14) from the conductive metal section (17).  Thus, the covered section (19) has the gradient composition structure wherein thermal expansion coefficient reduces toward the porous semiconductor layer (14) from the conductive metal section (17).
