摘要：
The present invention provides a solar cell that is useful for industry and has high photoelectric conversion efficiency and a method of manufacturing the same. A solar cell according to an aspect of the invention includes: a substrate; a buffer layer that is formed on the substrate and is composed of a group-III nitride semiconductor; and a group-III nitride semiconductor layer (p-type layer/an n-type layer) that has a p-n junction therein and is formed on the buffer layer. At least one of the buffer layer and the group-III nitride semiconductor layer having the p-n junction therein has a compound semiconductor layer formed by a sputtering method.
