Claims15
A photoelectric conversion element having a conductive film, a photoelectric conversion film, and a transparent conductive film in this order,
- wherein the photoelectric conversion film contains a compound represented by Formula (1),
- in Formula (1), R1 to R8 each independently represent a hydrogen atom or a substituent, B1 and B2 each independently represent an alkyl group or a heteroaryl group, A1 and A2 each independently represent a hydrogen atom or a substituent, at least one of A1 or A2 represents an aryl group or a heteroaryl group, and adjacent groups among R1 to R8, A1, A2, B1, and B2 may be linked to each other to form a ring.
A compound represented by Formula (2),
- in Formula (2), R1 to R8 each independently represent a hydrogen atom or a substituent, B3 and B4 each independently represent an alkyl group or a heteroaryl group, A1 and A2 each independently represent a hydrogen atom or a substituent, at least one of A1 or A2 represents an aryl group or a heteroaryl group, and adjacent groups among R1 to R8, A1, A2, B3, and B4 may be linked to each other to form a ring.
