Abstract:
1. A photoelectric conversion element comprising a first electrode, a photoelectric conversion layer comprising a semiconductor and a sensitizing dye, and a solid hole transport layer, and a second electrode, on a substrate, wherein said sensitizing dye is represented by the following general formula (1): wherein R R at least one of the hydrogen atoms in the ring b Z represents an organic residue having an acidic group, and an electron-attracting group or an electron-attracting ring structure; m is an integer from 3 to 4, and each ring may each independently have a substituent; said solid hole transport layer comprises a polymer obtainable by polymerizing a compound represented by the following formula or a multimer of one of the following formula: wherein X 1 and X 2 each independently represent a hydrogen atom, a linear or branched alkyl group having 6 to 18 carbon atoms, or —OR 4 group, R 4 represents a linear or branched alkyl group having 1 to 5 carbon atoms.
