Patent ID: 8471143

Claim:
A photoelectric conversion element comprising a pair of opposite electrodes having therebetween: a semiconductor layer containing a sensitizing dye which is supported by a semiconductor; and a charge transport layer, wherein the sensitizing dye is a compound represented by Formula (1), wherein Ar 1 and Ar 2 are each independently a substituted or unsubstituted arylene or heterocyclic group; R 1 and R 2 are each independently a substituted or unsubstituted alkyl, alkenyl, alkynyl, aryl or heterocyclic group, provided that R 1 , R 2 and Ar 1 may be combined to form a ring; R 3 , R 4 and R 5 are each independently a hydrogen atom, a halogen atom, a cyano group, a substituted or unsubstituted alkyl, alkenyl, alkynyl, alkoxy, amino, aryl or heterocyclic group; k and l are each independently an integer of 0 or more, provided that k+l≧1, and that when at least one of k and l is 2 or more, a plurality of R 3 s, R 4 s and Ar 2 s may be the same or different; m is an integer of 1 or more, and when m≧2, a plurality of R 3 s, R 4 s and Ar 2 s may be the same or different; R 6 is a hydrogen atom or a substituted or unsubstituted alkyl, alkenyl, alkynyl, aryl or heterocyclic group; R 7 is a group substituted with X and derived from an alkyl, alkenyl, alkynyl, alkoxy, alkylthio, alkylseleno, amino, aryl or heterocyclic group, provided that R 7 may have a substituent other than X; X is an acid group; n is an integer of 1 or more, provided that when n≧2; and a plurality of Xs may be the same or different, provided that a cis form and a trans form of a pair of R 3 and R 4 , and a pair of R 5 and N in an imidazolone ring with respect to each carbon to carbon double bond are included in Formula (1).
