Encapsulant For A Photovoltaic Module

Abstract: The present invention relates to an encapsulant for a photovoltaic module intended to coat a photovoltaic cell comprising at least two adjacent thermoplastic layers forming a core skin assembly characterized in that:  the skin layer consists of a polyamide grafted polymer comprising a polyolefin backbone representing from 50% to 95% by weight of the polyamide grafted polymer containing a residue of at least one unsaturated monomer (X) and at least one polyamide graft representing from 5% to 50% by weight of said polyamide grafted polymer  the core layer consists of a polyethylene chosen from a homopolymer of ethylene or a copolymer comprising at least 50 mol% of ethylene and one or more comonomers. The invention also relates to a photovoltaic module incorporating such an encapsulant.
