PROBLEM TO BE SOLVED: To use various transparent supports of low melting point so as to obtain a photoelectric conversion device excellent in photoelectric conversion efficiency, by a method wherein a photoelectric conversion device semiconductor film formed on a conductive support is thermally treated in the presence of sulfulic acid and then sensitized with dye. SOLUTION: In a photoelectric conversion device where a semiconductor film is formed on a conductive support, the semiconductor film is thermally treated in the presence of sulfuric acid and then sensitized with dye. A semiconductor layer is formed on a conductive support through a method where a dispersion solution or colloidal solution where semiconductor fine particles are dispersed is applied onto a conductive support, or semiconductor precursor is applied onto a conductive support and then hydrolyzed with moisture contained in the air into a semiconductor fine particles film. Polymethylene dye is preferably used as dye adsorbed by a semiconductor film, and dye is adsorbed by a semiconductor film through a method where a well-dried semiconductor film is dipped into a dye solution for a long time. |
