    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 units; (B) 0.01 to 3.00 wt.-% based on the overall weight of the polymer composition (I) of a compound according to Formula (I); wherein; R1, R1′, R2 and R2′ are each independently selected from the group consisting of hydrogen, n-alkyl, iso-alkyl, alkoxy, cycloalkyl, alkenyl, halogen and mixtures thereof; X is selected from the group consisting of primary amines, secondary amines, tertiary amines, hydrogen, alkyl, alkenyl and mixtures thereof. Furthermore, the present invention refers to the use of an encapsulation layer element comprising polymer composition (I) according to the invention for increasing the Pmax determined after 96 h according to IEC 60904, by applying the foil method with a temperature of 85° C. and relative humidity of 60% and a potential difference of 1500 V, of a photovoltaic module comprising besides the encapsulation layer element a protective front layer element, a photovoltaic cell element and a protective back element, whereby at least one of the protective elements comprises glass.
