<P>PROBLEM TO BE SOLVED: To provide an inexpensive dye-sensitized solar cell having improved photoelectric conversion efficiency. <P>SOLUTION: The dye-sensitized solar cell includes a photoelectrode using a stainless steel plate, and a counter electrode using a translucent conductive material. The photoelectrode using the stainless steel plate as a substrate which has a chemical composition containing Cr: 16 mass% or more and Mo: 0.3 mass% or more and whose roughened surface is formed with pitting-corrosive recesses and reconditioned at an arithmetic average roughness Ra of 0.2 μm or more, has a semiconductor layer supporting sensitizing dye on the roughened surface of the substrate. The counter electrode has a catalyst thin film layer formed on the surface of the translucent conductive material and having visible light permeability. The semiconductor layer of the photoelectrode and the catalyst thin film layer of the counter electrode face each other via electrolyte. <P>COPYRIGHT: (C)2011,JPO&INPIT |
