Abstract
The invention relates to a photoelectric conversion device, using oxide semiconductor fine particles sensitized with a methine dye represented by the following formula (1) and a solar cell using the same, and a solar cell high in conversion efficiency can be obtained at low cost: in the formula (1), n represents an integer of 0 to 7; Rrepresents an optionally-substituted aromatic residue or optionally-substituted aliphatic hydrocarbon residue, or an acyl group; X represents an optionally-substituted hydrocarbon residue which has 2 to 4 carbon atoms; Y represents a hydrogen atom, an optionally-substituted aromatic residue or aliphatic hydrocarbon residue, a carboxyl group or the like, and preferably represents a carboxyl group; Z represents an optionally-substituted aromatic residue or aliphatic hydrocarbon residue, or an acyl group; A, Aand Aeach independently represent a hydrogen atom, an optionally-substituted aromatic residue or aliphatic hydrocarbon residue or the like, and preferably represent a hydrogen atom; and a benzene ring a may have substituent(s) other than those shown in the above formula.
