<p>An organic photoelectronic conversion element having a sufficiently high open-circuit voltage can be produced by using a fullerene derivative comprising a structure represented by formula (1) and one or more structures selected from the group consisting of a structure represented by formula (2-1) and a structure represented by formula (2-2).
[wherein, ring A represents a fullerene skeleton, ring B represents a heterocyclic ring having a carbon number of 3 to 6, R represents a monovalent group, and k represents an integer of 1 to 8; and when there is a plurality of Rs, the Rs may be the same or different.]
[wherein, ring D represents an aromatic ring.]
