Abstract
A method of forming a lead-out electrode in an integrated-type photovoltaic device including photoelectric conversion cells connected to each other in series on a transparent substrate is to form a lead-out electrode portion or section by separating a laminate of a semiconductor photo-active layer and a back electrode layer into back electrode and lead-out portions by means of a scanned laser beam. The major part of the lead-out electrode portion is elongated and has, at the opposite end, enlarged sections for receiving external lead wires or conductors. Accordingly, the lead-out electrode portion occupies only a small area in the substrate and can be formed easily by scanning with a laser beam.
