Claim 0:
1. A photoelectric conversion element comprising
an anode, a cathode, an active layer provided between the anode and the cathode, and at least one electron transportation layer provided between the active layer and the cathode, wherein
one layer of the at least one electron transportation layer contains an insulating material and a semiconductor material; and a work function of the one layer (Wf1) and a work function of the cathode (Wf2) satisfy the following Formula (1):

Wf2−Wf1≥0.88 eV  (1);

the active layer contains a p-type semiconductor material and an n-type semiconductor material; and
the work function of the electron transportation layer (Wf1) and an energy level of a lowest occupied molecular orbital of the n-type semiconductor material (LUMO) satisfy the following Formula (2):

|LUMO|−Wf1≥0.06 eV  (2).
