Abstract
A photoelectric conversion device includes a light-absorbing layer including a compound semiconductor capable of photoelectric conversion, the compound semiconductor containing a group Ib element including Cu, a group IIIb element and a group VIb element; and a semiconductor layer on one surface-side of the light-absorbing layer, the semiconductor layer having a plane orientation different from that of the light-absorbing layer, the semiconductor layer containing a group Ib element including Cu, at least one element selected from Cd, Zn and In, and a group VIb element. The photoelectric conversion device includes a region in which Cu content decreases from the light-absorbing layer to the semiconductor layer across a junction interface.
