Patent ID: 7943848

Claim:
A photoelectric conversion element comprising an electrically conductive support having thereon an oxide semiconductor electrode comprising an oxide semiconductor which is adsorbed with a dye, and a counter electrode facing the oxide semiconductor electrode through a charge transfer layer, wherein the dye is represented by Formula (1): wherein R 2 represents a phenylene group; R 3 represents a hydrogen atom, an alkyl group, an aralkyl group, an alkenyl group, an aryl group or an aromatic heterocyclic group; R 4 represents an aryl group; R 5 represents a substituent; n2 and n3 each are 1 or 2; n2+n3=3; n4 is an integer of not less than 0; n5 is an integer of 0-4; and A represents a chain structure containing an electron withdrawing group and an acid group, provided that R 2 is p-conjugated with the acid group, or A represents a group represented by A 2 , wherein B represents a group of atoms necessary to form a single ring which may have a substituent, provided that the single ring is not condensed with another ring nor substituted with another ring; and X represents a group containing an acid group.
