Abstract
Official abstract text for this publication.
Provided is a photoelectric conversion element including: a lower electrode, a charge blocking layer which suppresses injection of a charge from the lower electrode, an organic layer which includes a photoelectric conversion layer, and an upper electrode which includes a transparent electrode layer, which are laminated in this order on a substrate. The photoelectric conversion layer is configured of an amorphous film and has a bulk hetero-structure of a P-type organic semiconductor and an N-type organic semiconductor formed of fullerenes. A difference between the ionization potential of the photoelectric conversion layer having the bulk hetero-structure and the electron affinity of the N-type semiconductor is 1.30 eV or greater.
