Latest Patents
Nakamura holds a patent for a solar cell element manufacturing method, solar cell element, and solar cell module. This patent describes a method for manufacturing a solar cell element that includes two different etching processes followed by the formation of a semiconductor layer. The process begins with etching a semiconductor substrate of the first conductor type using a first acid aqueous solution containing hydrofluoric acid, nitric acid, and sulfuric acid. Subsequently, the substrate is etched with a second acid aqueous solution that contains hydrofluoric acid and nitric acid, but with substantially no sulfuric acid, to create an uneven surface. Finally, a semiconductor layer of a second conductivity type, which is different from the first, is formed on at least a part of the uneven surface of the semiconductor substrate. This innovative approach contributes to the advancement of solar cell technology.
