摘要： A method of removing any short-circuit defect existing in a photoelectric conversion device such as solar batteries having a semiconductor layer which is disposed between an upper transparent electrode and a lower electrode and which produces an electromotive force when irradiated with a light. The method comprises applying a voltage between the photoelectric conversion device and a counter electrode across an electrolytic solution containing hydrogen ions and/or hydronium ions. The electrolytic solution is an aqueous solution of an electrolyte or electrolytes selected from a group consisting of inorganic acids, organic acids, inorganic bases, organic bases and salts of metals having standard electrode potential levels which are minus relative to the standard hydrogen electrode potential and which have absolute values greater than hydrogen super voltage.
