Abstract:
1. A stacked-layer type photoelectric conversion device comprising a plurality of photoelectric conversion units stacked on a substrate, each of which includes a one conductivity-type layer, a photoelectric conversion layer of substantially intrinsic semiconductor, and an opposite conductivity-type layer in this order from a light incident side, wherein at least one of said opposite conductivity-type layer in a front photoelectric conversion unit arranged relatively closer to the light incident side and said one conductivity-type layer in a back photoelectric conversion unit arranged adjacent to said front photoelectric conversion unit includes a silicon composite layer at least in a part thereof, and said silicon composite layer has a thickness of more than 20 nm and less than 130 nm and an oxygen concentration of more than 25 atomic % and less than 60 atomic %, and includes silicon-rich phase parts in an amorphous alloy phase of silicon and oxygen.
