<p>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 Ar1 and Ar2 are the same as or different from each other and represent a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group; X1 and X2 are the same as or different from each other and represent —O—, —S—, —C(═O)—, —S(═O)—, —SO2—, —C(R50)(R51)—, —Si (R3)(R4)—, —N(R5)—, —B(R6)—, —P(R7)—, or —P(═O)(R8)—; wherein the macromolecular compound has a light absorbing terminal wavelength of 700 nm or more.</p> |
