Abstract

For manufacturing a photovoltaic module (1) having on a transparent substrate (2) a transparent front electrode layer (3), a semiconductor layer (4) and a back electrode layer (5) as functional layers, the functional layers (3-5) are removed in the edge area (10) of the substrate (2) with a laser emitting infrared radiation. Subsequently, a back cover (12) is laminated on the coated substrate (2) with an adhesive film (11).
