Abstract
A photoelectric conversion device includes an organic photoelectric conversion layer, and suppresses sensitivity degradation caused by the light irradiation. A photoelectric conversion deviceis formed by stacking a first electrode layer, a photoelectric conversion layerincluding an organic material, and a second electrode layeron a substrate, in which the photoelectric conversion layerhas a bulk hetero structure of a P-type organic semiconductor and an N-type organic semiconductor, and a difference between an ionization potential of the P-type organic semiconductor and an apparent ionization potential of the bulk hetero structure is 0.50 eV or less. Accordingly, it is possible to suppress sensitivity degradation caused by the light irradiation.
