摘要： Provided is a charge-transporting composition for formation of an electrical charge-transporting thin film for use in a photoelectric conversion element, together with a non-fullerene active layer. The charge-transporting composition comprises: a charge-transporting substance composed of a polythiophene derivative containing a repeating unit represented by formula (1); an electron-accepting dopant substance; and a solvent. The electron-accepting dopant substance includes at least one of an arylsulfonic acid represented by formula (2) and a heteropoly acid.




(R1 and R2 are, mutually independently, a hydrogen atom, an alkoxy group, —O—[Z—O]p—Re, a sulphonic acid group, etc. p is an integer of 1 or greater, and Re is a hydrogen atom or an alkyl group, etc. that may be substituted with a sulphonic acid group, or the like.)




(A is a naphthalene ring, etc.; B is a divalent through tetravalent perfluorobiphenyl group; l is an integer that satisfies 1≤l≥4; and q is an integer of 2-4.)
