Abstract
Provided in one embodiment of the present invention is a solar cell upper electrode which is positioned on a photoactive layer and which includes a conductive polymer layer, wherein ionic liquid comes in contact with the surface of the conductive polymer layer so as to the post-treated, and, due to the post-treatment, an ion-exchange reaction occurs only in the upper area of the conductive upper electrode according to an embodiment of the present invention is not gelated so as to improve electrode performance, and does not oxidize a photoactive layer positioned under the electrode so as to be usable as an upper electrode, and thus can improve the performance of a solar cell to which the electrode is applied.
