Abstract
A method for manufacturing a solar cell capable of enhancing photoelectric conversion efficiency is provided. The present invention is a method for manufacturing a solar cell which includes steps of forming a p-n junction on a silicon semiconductor substrate and forming an aluminum oxide film on at least one main surface of the silicon semiconductor substrate, including: a step of subjecting the silicon semiconductor substrate to heat treatment in an atmosphere with 20 g or more water vapor per cubic meter and a temperature of 60° C. or more and 100° C. or less before the step of forming the aluminum oxide film. Consequently, a method for manufacturing a solar cell capable of enhancing photoelectric conversion efficiency is provided.
