Abstract
A photoelectric conversion device is disclosed. The photoelectric conversion device includes an electrode layer and a semiconductor layer. The semiconductor layer is located on the electrode layer and contains a group I-III-VI compound. In the semiconductor layer, an atomic ratio of a group I-B element to a group III-B element decreases from one principal surface side of the semiconductor layer on the electrode layer side to a central portion in a thickness direction and increases from the central portion to another principal surface side on a side opposite to the electrode layer.
