| titleOfInvention | Bilayer film of a photovoltaic module |
| abstract | Bilayer thermoplastic film of a photovoltaic module, comprising two layers of which one layer forms the encapsulant (22) and the other layer forms the backsheet (26), the encapsulant-backsheet assembly (22, 26) having a thickness greater than 100 μm (micrometer), characterized in that: a) the encapsulant (22) consists of a polyamide grafted polymer comprising a main polyolefin chain, representing 50% to 95% by mass of the polyamide grafted polymer, containing a moiety of at least one unsaturated monomer (X) and at least one polyamide graft, which represents 5% to 50% by mass of said polyamide grafted polymer, in which: - the polyamide graft is fixed to the main chain of polyolefin by the rest of the infatuated monomer (X) comprising a function capable of reacting by a condensation reaction with a polyamide having at least one amine limb and / or at least one carboxylic acid limb, - e The rest of the unsaturated monomer (X) is fixed to the main chain by grafting or copolymerization, - the main polyolefin chain and the polyamide graft being chosen so that said polyamide grafted polymer has a flow temperature greater than or equal to 75 ºC and less than or equal to 160 ºC, this flow temperature being defined as the highest temperature between the melting temperatures and the glass transition temperatures of the polyamide graft and the main polyolefin chain; b) the backsheet (26) comprises a layer formed by a polymer whose Young's modulus is greater than 1.1 GPa (ASTM D638), preferably greater than or equal to 1.3 GPa. |
