NOVELTY - A method of forming metallic pattern corresponding to raised features of an embosser (23) involves forming transparent conductive layer (21) on surface of transparent top layer of solar cell structure, the layer having an exposed surface; placing a metallic foil in proximity to the exposed surface of the conductive layer; and embossing the metallic pattern onto the exposed surface of the layer, the step of embossing including simultaneously applying pressure and heat to a portion of the metallic foil corresponding to the metallic pattern using the raised features of the embosser.    USE - For forming metallic pattern corresponding to raised features of an embosser (claimed); for manufacturing thin film solar cells.    ADVANTAGE - The method produces low resistance, highly conductive metallic foil finger patterns on solar cells, at the same time keeping the shadow losses to a minimum.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for roll to roll system (10) for forming a metallic pattern comprising a first process station for forming a solar cell structure, including a transparent conductive layer over a transparent top layer as a portion of a continuously fed roll-to-roll solar cell structure is advanced through the first process station; an assembly to hold and move a conductive foil over the continuously fed roll-to-roll solar cell structure; an embosser station having an embosser with raised surfaces to attach a section of the conductive foil to the transparent conductive layer by pressing raised features of the embosser against the metallic foil so that pressure and heat are simultaneously applied to a portion of the metallic foil interposed between the raised features and the transparent conductive layer, where the raised features are shaped in the form of the metallic pattern; and a moving assembly for holding and moving the continuously fed roll-to-roll solar cell structure through the first process station and the embosser station, where subsequent portions of the continuously fed roll-to-roll solar cell structure is unwrapped and fed from a supply roll, and the portions with attached metallic pattern are received and wrapped around a receiving roll.
