<p>The present invention provides a photovoltaic cell having a large short-circuit current density and a large photoelectric conversion efficiency. This photovoltaic cell comprises: a first electrode; a second electrode; and an active layer between the first electrode and the second electrode; wherein the active layer contains a 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, with at least one of Ar1 and Ar2 being 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)—; R50, R51, R3, R4, R5, R6, R7, and R8 are the same as or different from each other and represent a hydrogen atom, a halogen atom, or a monovalent organic group; and X1 and Ar2 are bonded with atoms adjacent to each other on a ring that constitutes Ar1, and X2 and Ar1 are bonded with atoms adjacent to each other on a ring that constitutes Ar2.</p> |
