Embodiment Construction

[0008] Hereinafter reference will be made to possible embodiments of the invention (see Figure 1-4 ) and explain the invention in detail with reference to possible embodiments.

[0009] figure 1 An exemplary structure of a photovoltaic module 24 is shown in which a solar cell system is encapsulated by the material 1 , 1 ′ used according to the invention. The encapsulation material 1, 1' consists essentially of a weather-resistant film 2, 2' and a carrier material 3, 3', on which the adjoining agent acts as an adhesion promoter to the sealing layer 5, 5' The film 4, 4'. The sealing layers 5 , 5 ′ produce a non-positive connection to the solar cell system 6 .

[0010] figure 2 A possible lamination device for producing the plastic composite used according to the invention is shown. A carrier material 3 selected according to the example is coated with an adhesive by means of a coating device 9 and bonded to a weather-resistant film 2 after passing through a dryer 10 . In ...

Abstract

The invention relates to the use of a polymer composite (1, 1'), comprising a backing material (3, 3'), selected from the group made up of polyethylene terephthalate (PET), polyethylene naphthenate (PEN) and ethylene-tetrafluoroethylene copolymer (ETFE), and layers of nylon 12 (2, 2', 4, 4') adjacent to the backing material on both sides, for producing photovoltaic modules.

Description

technical field [0001] The invention relates to the use of plastic composite materials for the production of photovoltaic modules. Background technique [0002] Photovoltaic modules are used to generate electrical energy from sunlight and consist of a laminate comprising a solar cell system as a core layer. This core layer is encapsulated by an encapsulation material which provides protection against mechanical and weather-induced influences. These materials can consist of one or more layers of glass and / or plastic films and / or plastic composites. [0003] Currently, film composites consisting of fluoropolymer film and polyester are used for weatherable film laminates according to the standard. In this case, the fluoropolymer film on the outside ensures weather resistance and the polyester film the mechanical stability and the required electrical insulation properties. Another fluoropolymer film on the inside is used in conjunction with the sealing layer of the solar cell...
