    摘要: 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.

    摘要: It is aimed to provide a photoelectric conversion device having high adhesion between a light-absorbing layer and an electrode layer as well as high photoelectric conversion efficiency. A photoelectric conversion device comprises a light-absorbing layer including a chalcopyrite-based compound semiconductor and oxygen. The light-absorbing layer includes voids therein. An atomic concentration of oxygen in the vicinity of the voids is higher than an average atomic concentration of oxygen in the light-absorbing layer.

    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.
