Abstract:
1. A method of producing a photovoltaic element comprising the steps of: immersing in an electrolytic solution a photovoltaic element comprising a back surface reflecting layer, a semiconductor layer and a transparent electrode layer successively stacked on a substrate; applying a forward voltage to the photovoltaic element to effect an electrolytic treatment to reduce the transparent electrode layer in a short-circuit portion of the photovoltaic element, thereby selectively removing a short-circuit current path in the photovoltaic element due to a defect, wherein a voltage gradient when the forward voltage applied to the photovoltaic element is caused to drop to 0 V or a such forward voltage as to effect no reduction reaction of the transparent electrode layer is −15 V/s to −0.1 V/s.
