Abstract:
1. A photoelectric conversion device, comprising oxide semiconductor fine particles sensitized with at least one dye represented by the following formula (1) having an acrylic acid part: wherein A1 and A2 each independently represent a carboxyl group, a cyano group, an alkoxycarbonyl group, an acyl group, a nitro group, a cyclic hydrocarbon residue which may be substituted, a heterocyclic residue which may be substituted, an amino group which may be substituted, a hydroxyl group, a hydrogen atom, a halogen atom or an alkyl group which may be substituted; X represents an aromatic hydrocarbon residue which may be substituted, a heterocyclic residue which may be substituted, or an organic metal complex residue which may be substituted; n represents an integer of from 1 to 6; when n is 2 to 6 and a plurality of A1 and a plurality of A2 are present, each A1 and each A2 independently represent any one of the groups or residues defined above for A1 and A2 which may be the same with or different from each other, and further, except for the A1 bond to the carbon atom to which the carboxyl group in an acrylic part is bound, two A1s or each A1 in a plurality of A1, two A2s or each A2 in a plurality of A2 and X may be bound together to form a ring selected from the group consisting of a benzene ring, a naphthalene ring, an indene ring, a pyridine ring, a pyrazine ring, a thiophene ring, a furan ring, an oxazole ring, a thiazole ring, an indole ring, a benzothiazole ring, a benzoxazole ring, a quinoline ring and a carbazole ring.
