NOVELTY - A dye-sensitized solar cell (1) consists of a photoelectrode (40) using a stainless steel plate (4), and a counter electrode (30) using a translucent electroconductive material (3). The photoelectrode has a base material formed by stainless steel plate containing chromium (16 %mass or more) and molybdenum (0.3 %mass or more), and has a chemical composition equivalent to ferrite type stainless steel type. A semiconductor layer (6) which supports a sensitizing dye (8) is provided on the roughened surface of the base material.    USE - Dye-sensitized solar cell.    ADVANTAGE - The dye-sensitized solar cell has excellent photoelectric conversion efficiency and economical efficiency.    DETAILED DESCRIPTION - A dye-sensitized solar cell consists of a photoelectrode using a stainless steel plate, and a counter electrode using a translucent electroconductive material. The photoelectrode has a base material formed by stainless steel plate containing chromium (16 %mass or more) and molybdenum (0.3 %mass or more), and has a chemical composition equivalent to ferrite type stainless steel type according to JIS G4305:2005. A semiconductor layer which supports a sensitizing dye is provided on the roughened surface of the base material having a roughened surface where pitting-corrosion-like recessed portion is formed and arithmetic mean deviation (Ra) is adjusted to 0.2 mu m or more. The counter electrode has a catalyst thin film layer (5) formed in the surface of translucent electroconductive material, and has visible-light transmittance. The semiconductor layer of photoelectrode and catalyst thin film layer of counter electrode face each other through an electrolyte solution (9). An INDEPENDENT CLAIM is included for manufacture of dye-sensitized solar cell.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the dye-sensitized solar cell.
