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 (10) comprises a light-absorbing layer (3) including a chalcopyrite-based compound semiconductor and oxygen. The light-absorbing layer (3) includes voids (3a) therein. An atomic concentration of oxygen in the vicinity of the voids (3a) is higher than an average atomic concentration of oxygen in the light-absorbing layer (3).
