Abstract
The present invention relates a photovoltaic module comprising a protective front layer element, an encapsulation layer element, a photovoltaic cell element and a protective back layer element, whereby at least one of the protective elements comprises glass; wherein the encapsulation layer element comprises a polymer composition (I) comprising at least the following components: (A) 97.00 to 99.99 wt.-% based on the overall weight of the polymer composition (I) of a polymer selected from an ethylene-vinylacetate copolymer, a polyolefin elastomer or a polymer of ethylene (a) selected from (a1) a copolymer of ethylene which bears functional groups containing units; (a2) a copolymer of ethylene comprising one or more polar comonomer unit(s) selected from (C1-C6)-alkyl acrylate or (C1-C6)-alkyl (C1-C6)-alkyl acrylate comonomer units, and optionally bears functional groups containing units different from said polar comonomer unit(s); (a3) a copolymer of ethylene comprising one or more alpha-olefin comonomer unit(s); and optionally bears functional groups containing units different from said polar comonomer unit(s) of polymer (a2); or mixtures thereof; and (b) silane group(s) containing u…
