摘要:
A double-layer thermoplastic film of a photovoltaic module, including two layers, one forms the encapsulator and the other forms the backsheet, wherein: a) the encapsulator is a layer including at least one polyolefin containing a polyethylene selected from a homopolymer of ethylene or a copolymer comprising at least 50 mol % of ethylene and at least one comonomer and between 0% and 100% of a polyamide grafted polymer comprising a polyolefin trunk that represents between 50 mass % and 95 mass % of the polyamide grafted polymer containing a radical of at least one unsaturated monomer (X) and at least one polyamide graft that represents between 5 mass % and 50 mass % of said polyamide grafted polymer; and b) the backsheet comprises a layer formed from a polyamide grafted polymer that is identical to that of the encapsulator except that it has a flow temperature higher than 160° C.
