摘要： The present invention provides a method of producing a photovoltaic element, which comprises a step of immersing a photovoltaic element having at least a first electrode layer, a semiconductor layer and a second electrode layer formed on a substrate into an electrolytic solution, and removing a short circuit current path caused by a defect in the photovoltaic element under the effect of an electric field, wherein the amount of a first ingredient and the amount of a second ingredient contained in the electrolytic solution are adjusted to control the concentration of hydrogen ions in the electrolytic solution, wherein the constituent substance of the second electrode layer is electrically dissolved by the first ingredient, and thereby it also provides a method of producing photovoltaic elements which is capable of reducing a leakage current caused by defect portions such as pin-holes existing in the photovoltaic elements with a large area to obtain photovoltaic elements with excellent photovoltage generation characteristics under a low illuminance.
