ABSTRACT:
A photoelectric conversion device using a semiconductor fine material such as a semiconductor fine particle sensitized with a dye carried thereon, characterized in that the dye is a methine type dye having a specific partial structure, for example, a methine type dye having a specific carboxyl-substituted hetero ring on one side of a methine group and an aromatic residue substituted with a dialkylamino group or an organic metal complex residue on the other side of the methine group, or a methine type dye having a carboxyl-substituted aromatic ring on one side of a methine group and a heteroaromatic ring having a dialkylamino group or an organic metal complex residue on the other side of the methine group; and a solar cell using the photoelectric conversion element. The photoelectric conversion element exhibits a conversion efficiency comparable or superior to that of a conventionally known photoelectric conversion element sensitized with a methine type dye.
