    • One subject of the invention is the use of a film as a protective backsheet in a photovoltaic module, said film comprising at least one layer of a composition containing a polyamide-grafted polymer, this polyamide-grafted polymer comprising a polyolefin backbone containing a residue of at least one unsaturated monomer (X) and at least one polyamide graft, in which: ° the polyamide graft is attached to the polyolefin backbone by the residue of the unsaturated monomer (X) that comprises a functional group capable of reacting via a condensation reaction with a polyamide having at least one amine end group and/or at least one carboxylic acid end group; ° the residue of the unsaturated monomer (X) is attached to the backbone by grafting or copolymerization; said polyamide-grafted polymer comprising, relative to its total weight: ° from 40 to 95% by weight of the polyolefin backbone comprising the unsaturated monomer (X); and ° from 5 to 60% by weight of polyamide grafts, and the melting point or glass transition temperature of the polyamide grafts being greater than or equal to 85°C. The invention also relates to a process of manufacturing a photovoltaic module, to a photovoltaic module and also to the use of this module for producing electricity.
