ABSTRACT:
A process for producing a light absorption layer of a solar cell is disclosed, in which prior to heat-treatment, at least two of the following steps are performed in combination: (1) electrodeposition of a copper layer including selenium particles, (2) electrodeposition of an indium layer including selenium particles, (3) electrodeposition of a copper layer not including selenium, and (4) electrodeposition of an indium layer not including selenium. Control of copper, indium, and selenium contents becomes easier with this process.
