Photovoltaic module comprising a polymer and method of film making such a module

A photovoltaic module comprising: - the front plates (2) and rear (3), each having inner (2a) and external (3a), - a plurality of photovoltaic cells (4), arranged side by side between the front plate (2) and rear (3) and each having an antireflection layer, - and a sealing gasket (5) device disposed between the front plates (2) and rear (3) around the photovoltaic cells (4) .The portion the internal face (2a) of the front plate (2), delimited by the seal (5) is coated with a polymer film (7) having a refractive index between that of the front plate (2) and the antireflection layers of solar cells (4), said film (7) being in contact with the photovoltaic cells (4).
