<P>PROBLEM TO BE SOLVED: To provide a photoelectric conversion element having high short-circuit current density and photoelectric conversion efficiency. <P>SOLUTION: The photoelectric conversion element includes a first electrode, a second electrode, and an active layer between the first electrode and the second electrode. The active layer contains a compound having a structural unit represented by formula (1). [In the formula, Ar<SP POS="POST">1</SP>and Ar<SP POS="POST">2</SP>may be the same or different and each represents a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group, where at least one of Ar<SP POS="POST">1</SP>and Ar<SP POS="POST">2</SP>represents a trivalent heterocyclic group. X<SP POS="POST">1</SP>and X<SP POS="POST">2</SP>may be the same or different and each represents -O-, -S-, -C(=O)-, -S(=O)-, -SO<SB POS="POST">2</SB>-, -C(R<SP POS="POST">50</SP>)(R<SP POS="POST">51</SP>)-, -Si(R<SP POS="POST">3</SP>)(R<SP POS="POST">4</SP>)-, -N(R<SP POS="POST">5</SP>)-, -B(R<SP POS="POST">6</SP>)-, -P(R<SP POS="POST">7</SP>)- or -P(=O)(R<SP POS="POST">8</SP>)-.] <P>COPYRIGHT: (C)2012,JPO&INPIT |
