Summary: | To provide a manufacturing method for a solar cell with excellent open-circuit voltage, a multi-junction type solar cell, a solar cell module, and a solar power generation system.SOLUTION: A manufacturing method for a solar cell includes the steps for forming a p-electrode on a substrate, forming a film mainly composed of copper suboxide and/or a composite oxide of copper suboxide on the p-electrode, and performing an oxidation process on the film mainly composed of copper suboxide and/or a composite oxide of copper suboxide. In the oxidation process, the oxygen partial pressure is 5000 [Pa] or more and 200000 [Pa] or less. In the oxidation process, the water vapor concentration is 9.4×10-1[g/m3] or more and 2.5×103[g/m3], the process temperature is 40 [°C] or more and 150 [°C] or less. In the oxidation process, the process time is 5 minutes or more and 150 minutes or less.SELECTED DRAWING: Figure 3
