Abstract

The present invention relates to a method for manufacturing a solar cell having excellent long-term reliability and high efficiency, said method including: a step () for applying a paste-like electrode agent to an antireflection film formed on the light receiving surface side of a semiconductor substrate having at least a pn junction, said electrode agent containing a conductive material; and an electrode firing step () having local heat treatment (step ()) for applying heat such that at least a part of the conductive material is fired by irradiating merely the electrode agent-applied portion with a laser beam, and whole body heat treatment (step ()) for heating the whole semiconductor substrate to a temperature below 800° C.
