Abstract
A method for manufacturing a solar cell comprising forming a p-electrode on the substrate, forming a film containing cuprous oxide and/or a complex oxide of cuprous oxides as a main component on the p-electrode, and oxidizing the film containing the cuprous oxide and/or the complex oxide of cuprous oxides as a main component. A partial pressure of oxide of the oxidizing is 100 [Pa] or more and less than 5000 [Pa]. A temperature of the oxidizing is 100 [degrees Celsius] or more and 300 [degrees Celsius] or less. A duration time of the oxidizing is 1 [sec] or more and 90 [min] or less.
