Definitions

  • the invention relates to the use of polyamide as an encapsulating material for photovoltaic modules.
  • Photovoltaic modules are used to generate electrical power.
  • part of the structure of photovoltaic modules comprises solar cells which, by exposure to sunlight, generate electrical charges which can be drawn off as current.
  • these solar cells are sensitive to mechanical influences or weathering influences to different extents.
  • Encapsulating materials are used in order to protect said solar cells from these influences. These materials can consist of one or more layer(s), made of glass and/or plastic composites.
  • composites of fluoropolymer materials and polyester (PET) are used as standard for encapsulating materials.
  • a fluoropolymer layer on the outside guarantees weathering resistance
  • the PET film in the core guarantees the mechanical stability and the electrical insulation
  • another fluoropolymer layer on the inside guarantees the connection to the embedding material of the solar cells.
  • the adhesion to the embedding material e.g. ethylvinyl acetate (EVA) is low.
  • EVA ethylvinyl acetate
  • relatively thick composites are required to ensure the desired electrical insulation. This is attributable on the one hand to the low insulating capacity of fluoropolymer layers and on the other hand, to the adhesive layers used as standard between the films.
  • the smallest irregularities or inclusions in the adhesive layers have the result that high currents flow in a punctiform manner. This phenomenon must be counteracted by a larger thickness of the PET film in the core as a precaution.
  • the present invention wishes to remedy this.
  • polyamide as an encapsulating material for the production of photovoltaic modules is provided according to the invention.
  • polyamide is advantageously effected as a film or as a film composite containing polyamide (PA).
  • PA polyamide
  • plastic composite comprising a carrier material selected from the group of polyethylene terephthalate (PET), polyethylene naphthenate (PEN) or ethylene tetrafluoroethylene copolymer (ETFE), as well as polyamide-12 layers adjoining the carrier material on both sides.
  • PET polyethylene terephthalate
  • PEN polyethylene naphthenate
  • ETFE ethylene tetrafluoroethylene copolymer
  • polyamide makes it possible to achieve very good adhesion to the embedding material which, as described above, can be, for example, EVA.
  • the electrical insulation can be improved significantly by using a polyamide single film with the same thickness as compared to a composite comprising fluoropolymer layers and PET. It is not possible for high currents to flow in a punctiform manner via defects or inclusions in the adhesive layers.
  • Polyamide films can likewise be designed as weather- and UV-stabilised so that values comparable to those when using fluoropolymers can also be achieved with regard to these properties.
  • Various colour combinations can also be adjusted by means of pigmentation.
  • two production steps i.e. the production of the PET/fluoropolymer layer composite and the fluoropolymer layer/PET/fluoropolymer layer composite can be saved.
  • FIGS. 1 to 5 The invention is explained in detail hereinafter with reference to possible embodiments—see FIGS. 1 to 5 —as well as with reference to a possible exemplary embodiment.
  • FIG. 1 shows the exemplary structure of a photovoltaic module which is encapsulated with the material 1 used according to the invention.
  • the encapsulating material 1 comprises a weather-resistant film which at the same time serves as an adhesion promoter to the embedding material 2 .
  • the embedding material 2 produces the non-positive connection to the solar cells 3 and to the embedding material 2 ′.
  • the embedding material 2 ′ further ensures the non-positive connection to the encapsulating material 4 .
  • FIG. 2 shows the exemplary structure of a photovoltaic module which is encapsulated with the material 1 used according to the invention.
  • the encapsulating material 1 is used on both sides of the solar cells 3 .
  • FIG. 3 shows the exemplary structure of a photovoltaic module which is encapsulated with the material 1 used according to the invention.
  • a fluoropolymer layer 5 is used as an additional layer to the encapsulating material 1 on the side facing away from the solar cells 3 .
  • the fluoropolymer layer 5 and the encapsulating material 4 thus constitute the respectively outermost layer of the photovoltaic module.
  • FIG. 4 shows the use according to the invention of a plastic composite 1 , 1 ′ with the polyamide 12 layers 12 which are disposed on both sides of the carrier material 13 .
  • the carrier material consists of polyethylene terephthalate or polyethylene naphthenate or ethylene tetrafluoroethylene copolymer.
  • FIG. 5 shows a possible laminating device for producing a non-positive composite 6 from the materials 1 and 5 according to FIG. 3 .
  • the encapsulating material 1 which is selected according to the exemplary embodiment is coated with adhesive by means of the applicator unit 7 and after passing through a drier 10 is adhesively bonded to the fluoropolymer layer 5 .
  • the contact between the two films is controlled by the pressing pressure between the rollers 11 .
  • the material 1 can be pre-treated by means of physical media 9 before each production step.
  • the non-positive connection between the encapsulating material 1 and the fluoropolymer layer 5 can also be produced by co-extrusion. In this case, it is also possible to insert an adhesion promoter layer between the materials 1 and 5 and thus produce a triple-layer co-extrudate.
  • the encapsulating material 1 itself can comprise a monolayer or likewise a co-extrudate of several layers.
  • the material 1 Before using the encapsulating material 1 according to the invention or also before adhesive bonding with the fluoropolymer layer 5 , the material 1 can be pre-treated by means of chemical or physical media. This pre-treatment can be implemented on one or also on both sides of the encapsulating material 1 .
  • Encapsulating material 1 as film polyamides (PA) of the type polyamide 6, polyamide 66, polyamide 7, polyamide 9, polyamide 10, polyamide 11, polyamide 12, polyamide 69, polyamide 6 10, polyamide 6 12, PA-6-3-T, PA 6I, polyphthalamide (PPA) as well as other possible aromatic, partially aromatic and co-polyamides comprising these types.
  • PA polyamides
  • PA polyphthalamide
  • Embedding material 2 , 2 ′ ethylvinylacetate (EVA), polyvinylbutyral (PVB), ionomers, polymethylmethacrylate (PMMA), polyurethane, polyester, hotmelt or silicone elastomers.
  • EVA ethylvinylacetate
  • PVB polyvinylbutyral
  • PMMA polymethylmethacrylate
  • polyurethane polyester, hotmelt or silicone elastomers.
  • Encapsulating material 4 glass
  • PVDF polyvinylfluoride
  • ECTFE ethylenechloro trifluoroethylene
  • PCTFE polychlorotrifluoroethylene
  • ETFE ethylenetetra-fluoroethylene
  • PTFE polytetrafluoroethylene-hexafluoropropylene-vinylidenefluoride
  • Fluoropolymer layer 5 as coating fluoropolymer from the group of selectively soluble fluoropolymers.
  • the photovoltaic modules constructed from the aforesaid components are extremely stable when used outside which can be attributed, inter alia, to the good adhesion of polyamide to the embedding material.
