Patent ID: 8105868

Claim:
A method for making a solar cell module comprising solar cells connected in series, the module comprising a first electrode layer, an active layer, and a second electrode layer, wherein at least one of the first and second electrode layers comprises a transparent conductive oxide layer, the method comprising the steps of: a) making, in a system comprising at least a substrate overlaid by a first electrode layer, which first electrode layer is overlaid by an active layer, at least one pair of an interrupt in the first electrode layer and the active layer and an interconnection groove through the active layer; b) providing an insulating compound filling the interrupt; c) applying a lift-off compound onto the active layer at a position adjacent to the interconnection groove on an other side of the interconnection groove from the interrupt; d) applying the second electrode layer over the active layer, the insulating compound and the lift-off compound; and e) removing the lift-off compound and a portion of the second electrode at the position adjacent to the interconnection groove to obtain a groove in the second electrode layer; wherein the interrupt, the interconnection groove, the insulating compound and the lift-off compound are simultaneously applied at fixed relative distances.
