Abstract:
A solar cell element and method of manufacturing same is disclosed. A reverse-conductive-type layer is formed on at least one part of a first surface side of a one-conductive-type semiconductor substrate. A conductive layer is formed on the reverse-conductive-type layer. A contact region for electrically connecting the conductive layer and the one-conductive-type semiconductor substrate is formed by heating and melting at least one part of the conductive layer. The solar cell element can be manufactured without conducting complicated treatments, such as removal by etching and re-growing of a silicon thin layer.
