Abstract

A solar cell manufacturing method according to the present invention is a solar cell manufacturing method that forms a transparent conductive film of ZnO as an electric power extracting electrode on a light incident side, the method comprises at least in a following order: a process A forming the transparent conductive film on a substrate by applying a sputtering voltage to sputter a target made of a film formation material for the transparent conductive film; a process B forming a texture on a surface of the transparent conductive film; a process C cleaning the surface of the transparent conductive film on which the texture has been formed using an UV/ozone; and a process D forming an electric power generation layer on the transparent conductive film.
