Claim Text:
1. A method for manufacturing a foil-like electrical connector for connecting solar cells to form at least one solar module, the method comprising: providing an insulating carrier film sheet having a width which essentially corresponds to the width of the solar cells to be connected; subsequently introducing into the carrier film sheet (i) recesses in an area corresponding to future soldering points, and (ii) adjustment and transport perforations into side strip edge areas; providing a conductive foil sheet having a width corresponding to the carrier film sheet, wherein (i) adjustment and transport perforations are introduced into the conductive foil sheet at side strip edge areas, (ii) comb structures configured to function as electrical connection fingers are provided in the conductive foil sheet, and (iii) retaining webs are provided in a direction of the adjustment and transport perforation to ensure secure positioning of the comb structures; positioning the conductive foil sheet on the carrier film sheet with the aid of pin-shaped extensions of one of a transport belt or a transport roller, the extensions engaging in the corresponding adjustment and transport perforations of the conductive foil sheet and the insulating carrier film sheet; joining the carrier film sheet to the conductive foil sheet via an adhesive bond to form a composite sheet; separating the side edge strips and severing the retaining webs; laminating an insulating cover film at each side edge of the composite sheet, the cover film having lateral overhangs in relation to the side edges of the composite sheet; and folding the lateral overhangs of the cover film and fixing the folded lateral overhangs to the bottom side of the composite sheet to form the foil-like electrical connector, wherein the folded lateral overhangs insulate the edges of the composite sheet.
