Embodiment Construction

[0050] figure 1 A schematic cut-away view of the integrated system for optoelectronic interaction of the present invention is shown. The support foil 2 , which can be made, for example, of polyvinyl butyral (PVB), carries the other functional layers and forms a sealing layer that protects the module from the external environment. On this layer a metal layer 3 is adhered thereto. The metal layer can be made of tin, its thickness is greater than 5 μm, and has a conductor structure device ( figure 2 ). This layer plays the role of photocell connection, and is used as a bus line, and at the same time as a reflector. There is an insulating layer 4 on the metal layer, which is used to insulate the metal layer from the photovoltaic cell. With the aid of an adhesive, the active layer 5 , such as a wafer or thin-film photovoltaic cell, is connected to the insulating layer 4 . The insulating layer 4 has to be broken where there is an electrical connection (not shown). The light 7...

Abstract

The present invention relates to a composite system for photovoltaic (PV) modules. The composite system consists of a carrier foil, a metal foil applied onto the carrier foil, and an insulating layer applied onto the metal foil. Using different connecting techniques, different photovoltaic (PV) cells can be fastened to the composite system and electrically interconnected thereby. In addition, the invention relates to a method for producing the composite system for PV modules, and to the use of the composite system for the back side contacting of wafer cells that have both contacts on the same side and that are placed, with the contacts, onto conductor structures that interconnect them into a module, and to the use of the composite system for modules of internally interconnected thin-film cells.

Description

technical field [0001] The present invention relates to an integrated system for optoelectronic interaction. The system consists of a support sheet, a metal sheet and an insulating layer, wherein the metal sheet is mounted on the support sheet, and the insulation layer is mounted on the metal sheet. Different photovoltaic cells can be fixed on the integrated system of the present invention through different connection techniques, and thus electrically connected. [0002] Furthermore, the invention also relates to a production method for the production of an integrated system for photovoltaic action, as well as the use of the integrated system in connection with the reverse side of a cell wafer module, said photovoltaic cell simultaneously having two contacts on one side, respectively and through These contacts are connected to the conductor structure means and thus to a module. The invention additionally relates to the use of said integrated system in interconnected thin-fil...
