Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 0:
1. A photoelectric conversion element, comprising:
a first electrode including a plurality of electrodes independent from each other;
a second electrode disposed to be opposed to the first electrode;
an n-type photoelectric conversion layer including a semiconductor nanoparticle, the n-type photoelectric conversion layer being provided between the first electrode and the second electrode;
a semiconductor layer including an oxide semiconductor material, the semiconductor layer being provided between the first electrode and the n-type photoelectric conversion layer,
wherein a carrier density of the n-type photoelectric conversion layer is higher than a carrier density of the semiconductor layer; and
an insulation layer provided between the first electrode and the semiconductor layer,
wherein the first electrode includes a charge readout electrode and a charge accumulation electrode, the charge readout electrode being electrically coupled to the n-type photoelectric conversion layer via an opening provided to the insulation layer, and the charge accumulation electrode being disposed to be opposed to the n-type photoelectric conversion layer with the insulation layer interposed therebetween.
