Abstract
The invention relates to the use in a photovoltaic module of a film of a composition as a backsheet or as an encapsulant, this composition comprising, with respect to the total weight of the composition: from 1 to 99% of a polyethylene having an ethylene whose level by weight is greater than or equal to 80% chosen from the homopolymers of ethylene and the copolymers of ethylene and another alpha-olefin; from 99 to 1% of a polyolefin B, other than A, carrying a reactive functional group X chosen from the anhydride carboxylic acids and epoxides. The invention further relates to a photovoltaic module comprising the film of the composition according to the invention and also a process for the manufacture of this module.
