Abstract
A method for evaluating performance of a solar cell, comprising: a current passing step (S) of passing, in a forward direction, a direct current with respect to a solar cell element constituting the solar cell; a temperature control step (S) of heating the solar cell element and controlling a heating temperature of the solar cell element; and a light emission detecting step (S) of detecting light emission characteristics of light generated from the solar cell element due to the passing of the direct current in the current passing step and the heating of the solar cell element in the temperature control step (S).
