Patent ID: 7851695

Claim:
A stacked-type photoelectric conversion device comprising an amorphous silicon-based photoelectric conversion unit and a crystalline silicon-based photoelectric conversion unit stacked thereon or vice versa, wherein an amorphous photoelectric conversion layer included in said amorphous photoelectric conversion unit has a thickness of at least 0.03 μm and less than 0.17 μm, and a crystalline photoelectric conversion layer included in said crystalline photoelectric conversion unit has a thickness of at least 0.2 μm and not more than 0.7 μm, and a silicon oxide layer of a first conductivity type included in said amorphous photoelectric conversion unit and a silicon layer of a second conductivity type included in said crystalline photoelectric conversion unit makes a junction, the silicon oxide layer having an oxygen content of at least 35 atomic %, wherein said silicon oxide layer of the first conductivity type has a thickness of at least 5 nm and less than 20 nm, wherein a transparent electrode layer, said amorphous photoelectric conversion unit, and said crystalline photoelectric conversion unit stacked in this order on a transparent insulating substrate are separated by a plurality of parallel linear isolation grooves so as to form a plurality of strip-like stacked-type photoelectric conversion cells, and the plurality of cells are electrically connected and integrated in series via a plurality of connection grooves extending in parallel with said isolation grooves.
