PHOTOELECTRIC CONVERSION DEVICE

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.
