Abstract

The present invention provides a macromolecular compound by which the short-circuit current density and the photoelectric conversion efficiency are enhanced when the macromolecular compound is used in an organic layer contained in a photovoltaic cell. Specifically, the present invention provides a macromolecular compound having a structural unit represented by Formula (1):

wherein Ar 1 and Ar 2 are the same as or different from each other and represent a trivalent heterocyclic group; X 1 represents —O—, —S—, —C(═O)—, —S(═O)—, —SO 2 —, —Si(R 3 )(R 4 )—, —N(R 5 )—, —B(R 6 )—, —P(R 7 )—, or —P(═O)(R 8 )—; and R 51 represents an alkyl group having 6 or more carbon atoms, an alkyloxy group having 6 or more carbon atoms, an alkylthio group having 6 or more carbon atoms, an aryl group having 6 or more carbon atoms, an aryloxy group having 6 or more carbon atoms, an arylthio group having 6 or more carbon atoms, an arylalkyl group having 7 or more carbon atoms, an arylalkyloxy group having 7 or more carbon atoms, an arylalkylthio group having 7 or more carbon atoms, an acyl group having 6 or more carbon atoms, or an acyloxy group having 6 or more carbon atoms.
