Abstract: Disclosed is a method for manufacturing a solar cell, which is capable of enhancing the conductivity of a molybdenum thin film by decreasing the specific resistivity and thickness of the molybdenum thin film that is a back electrode. The method for manufacturing the solar cell according to the present invention includes: a step of forming a molybdenum thin film on a substrate; and a step of performing a post-processing process on the molybdenum thin film to form a back electrode. Here, the post-processing process with respect to the molybdenum thin film may be performed by irradiating an electron beam.
