    • PROBLEM TO BE SOLVED: To improve the efficiency of photoelectric conversion by forming a non-single crystal semiconductor layer with reduced defects as a semiconductor layer constituting unit cells of a photoelectric conversion device. SOLUTION: The photoelectric conversion device includes one or more units cells between the first and second electrodes and each unit cell constructs a semiconductor junction made by sequentially laminating a first impurity semiconductor layer of one conductivity type; an intrinsic non-single crystal semiconductor layer; and a second impurity semiconductor layer reverse in conductivity type to the first impurity semiconductor layer. In the unit cells disposed on the light incidence side, the non-single signal crystal semiconductor layer contains nitrogen in a concentration range of ≥5×10 18 /cm 3 and ≤5×10 20 /cm 3 when measuring a concentration by a secondary ion mass analyzing method, and contains oxygen and carbon of 18 /cm 3 in concentration.
