    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.

    摘要: It is an object of the present invention to provide a method for manufacturing a semiconductor layer, a method for manufacturing a photoelectric conversion device, and a semiconductor layer forming solution which are able to easily manufacture a good semiconductor layer having a desired thickness. To accomplish this object, a starting solution containing a metallic element, a chalcogen organic compound and a Lewis base organic compound is initially produced. Next, heating the starting solution produces fine particles. The fine particles contain a metal chalcogenide which is a compound of the metallic element and a chalcogen element included in the chalcogen organic compound. A semiconductor layer is formed by using a semiconductor layer forming solution in which the fine particles are dispersed.
