| 摘要 |
The invention relates to a backsheet for a photovoltaic module, containing a polyamide and characterised in that said backsheet also contains a terpolymer consisting of acrylester, styrene and acrylonitrile (ASA), and also to a composite film that has an at least dual-layered structure, in which . (a) layer 2 contains one or more polymers which is (are) selected from the group: PET (polyethylene terephthalate), PBT (polybutylene terephthalate), PPO (polyphenylene oxide), PEN (polyethylene naphthalate), PVF (polyvinyl fluoride), ETFE (ethylene tetrafluoroethylene), PP (polypropylene), PMMA (polymethyl methacrylate), PC (polycarbonate), PI (polyimide), POM (polyoxymethylene), PA (polyamide), ASA (acrylester styrene acrylonitrile), COC (cyclic olefin copolymer) and PEI (polyetherimide), and . (b) layer 1 is a backsheet according to one of claims 1 to 6, adjoins layer 2, and if required adheres thereto or is connected thereto by means of an adhesion promoter. The invention also relates to a photovoltaic module that comprises this backsheet or composite film. |
