Abstract

In the present invention, a p-type silicon substrate is produced, a solution containing aluminum is misted, and the misted solution is sprayed onto the back surface of the p-type silicon substrate under non-vacuum to form a back surface passivation film made of the aluminum oxide film on the back surface of the p-type silicon substrate. Thereafter, a light irradiation processing in which an interface between the p-type silicon substrate and the back surface passivation film is irradiated with ultraviolet light is performed.
