摘要：
It is an object to provide a photoelectric conversion device with high photoelectric conversion efficiency. The photoelectric conversion device includes an electrode layer, and a light absorbing layer located on the electrode layer. The light absorbing layer is comprised of a plurality of stacked semiconductor layers containing a chalcopyrite-based compound semiconductor. The semiconductor layers contain oxygen. A molar concentration of the oxygen in surfaces and their vicinities of the semiconductor layers where the semiconductor layers are stacked on each other is higher than average molar concentrations of the oxygen in the semiconductor layers.
