SOLAR CELL MANUFACTURING METHOD

摘要

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 (7) 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 (9) having local heat treatment (step (9a)) for applying heat such that at least a part of the conductive material is fired by irradiating only the electrode agent-applied portion with a laser beam, and whole body heat treatment (step (9b)) for heating the whole semiconductor substrate to a temperature below 800°C.
