Abstract: The use of a multilayer polyamide film as a rear protective sheet in a photovoltaic module. Also, a photovoltaic module containing photovoltaic cells protected by an encapsulant, a front protective layer, and a rear protective layer, wherein the rear protective layer is formed by a multilayer polyamide film including: a CA layer including, as predominant polymer, at least one polyamide A exhibiting a mean number of carbon atoms per nitrogen atom of between 4 and 8, a CB layer including: (a) as predominant polymer, at least one polyamide B exhibiting a mean number of carbon atoms per nitrogen atom of between 8 and 15, the polyamide(s) B exhibiting a mean number of carbon atoms per nitrogen atom which is strictly greater than the mean number of carbon atoms per nitrogen atom of the polyamide(s) A, and (b) at least one additive for combating UV radiation.
