Abstract
A method for manufacturing a solar cell according to an embodiment includes 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 5000 [Pa] or more and 200000 [Pa] or less. A concentration of vapor water of the oxidizing is 9.4×10[g/m] or more and 2.5×10[g/m] or less. A temperature of the oxidizing is 40 [degrees Celsius] or more and 150 [degrees Celsius] or less. A duration time of the oxidizing is 10 [sec] or more and 150 [min] or less.
