Patent ID: 7728222

Claim:
A photoelectric conversion device comprising oxide semiconductor fine particles sensitized with a compound represented by the following formula (2) {wherein A1, A2 and A3 each independently is an unsubstituted or substituted aromatic hydrocarbon residue, an unsubstituted or substituted amino group, hydroxyl group, hydrogen atom, halogen atom or cyano group; X1, X2 and X3 each independently is oxygen atom or sulfur atom, selenium atom; Y is a mono- or di-substituted aminophenyl group where the amino group is substituted with a phenyl group or an unsubstituted C1 to C20 alkyl group; or a mono- or di-substituted amino group where one of the substituents is a phenyl group and in the case where the amino group is di-substituted, the other substituent is an alkyl group or a phenyl group, or a piperidino group; n is an integer of zero or 1 to 2; when n is 2 whereby a plurality of A2 and A3 are present, each of A2 and each of A3 may be same or different and each shows the above-mentioned groups; and A1, A2 (including the case where a plurality thereof are present) and A3 (including the case where a plurality thereof are present) may form a ring being bonded by a plurality of groups therein and the ring formed as such may be substituted}.
