Abstract
The present invention provides a method for manufacturing a solar cell including: preparing a semiconductor silicon substrate which has an electrode, which is formed by baking an electrode precursor containing Ag powder on at least one main surface, has a PN junction, and is less than 100° C.; and performing an annealing treatment to the semiconductor silicon substrate at 100° C. or more and 450° C. or less. Consequently, there is provided the method for manufacturing a solar cell which suppresses a degradation phenomenon that an output of the solar cell is lowered when the solar cell is left as it stands at a room temperature in the atmosphere.
