摘要

The present invention addresses the problem of providing: a method for reactivating a counter electrode active material for a dye-sensitive solar cell capable of preventing a decrease in the power generation performance of a dye-sensitive solar cell, the method for reactivating a counter electrode active material allowing the temporarily decreased power generation performance of the dye-sensitive solar cell to be restored to the initial performance by regenerating an electroconductive polymer reduced by a redox pair in an electrolyte in the dye-sensitive solar cell; a method for regenerating a dye-sensitive solar cell in which said method is used; a catalyst layer for a dye-sensitive solar cell; a counter electrode; an electrolyte; and a dye-sensitive solar cell. The present invention is a method for reactivating a counter electrode active material for a dye-sensitive solar cell having a counter electrode configured from a catalyst layer that contains at least one electroconductive polymer as the counter electrode active material, wherein the method for reactivating a counter electrode active material for a dye-sensitive solar cell includes re-oxidizing the electroconductive polymer by chemical or electrochemical oxidation.
