A process for the preparation of a film-like electrical connector for solar cells, which is produced in such a connection element as well as a method for the electrical connection of at least two solar cells to a solar module

摘要

The invention relates to a method for the manufacture of a film-like electrical connector for solar cells, in order to modules to be connected, wherein the connector is a conductive and has at least one insulating layer. In accordance with the invention, first an insulation rene carrier film web in a width is provided, which essentially the width of the solar cells to be switched imposes corresponds to. Furthermore, in the film support recesses in the area of later solder points and in the sides strip edge areas of adjustment - and transport rows of holes or perforations. Furthermore, a conductive film web with a width which is matched to the carrier film is provided, which is likewise in this film web on the edge side, an adjustment - and transportation perforation, as well as additional comb structures introduced as a later electrical connection fingers are designed. In this case, retaining webs remain in the direction of the adjustment - and transportation perforation, in order to ensure a secure the position of the comb structures. With the aid of pin-shaped extensions of a conveyor belt or a transporting roller, the conductive film web on the carrier film is positioned, wherein the projections into the respective adjustment - and transportation perforations engage. Thereafter, a connection of the carrier film with the conductive film web, preferably by material engagement. Subsequently, a separation of the side edge strips and cutting out of the retaining fins. In the next step, an application, in particular to be laminated onto an insulating cover foil or in each case of a peripheral deck films strip, each with a wide projection based on the composite support film / conductive film web. After this is followed by a folding and fixing of the laterally projecting deck films edges or of the projection of the deck films strip up to the bond between side for the purpose of the edges of the insulation at. The product obtained in this way is then applied to a supply roll is mounted for the later processing.
