ABSTRACT:
A photoelectric conversion device comprising, on a substrate, a photoelectric conversion element having in lamination, a first electrode layer, a first insulating layer for blocking carriers of first conduction type and second conduction type from passing therethrough, a photoelectric conversion semiconductor layer, a second insulating layer for blocking carriers of first conduction type and second conduction type from passing therethrough, and second electrode layers and a switch element having laminated a gate electrode layer, a third insulating layer, a semiconductor layer, an ohmic contact layer, a pair of first and second main electrode layers, and a wiring layer for electrically connecting first or second electrode layer of photoelectric conversion element to first main electrode layer of the switch element can be provided with high SN ratio and at lower cost without providing the injection blocking layer.
