    摘要: The subject of the invention is a transparent substrate (6) having at least one antireflection coating, made from a film (A) comprising multiple thin layers of alternately high and low refractive indexes.The multilayer film comprises, in succession: a high-index first layer (1), having a refractive index n1 of between 1.8 and 2.3 and a geometrical thickness e1 of between 5 and 50 nm; a low-index second layer (2), having a refractive index n2 of between 1.30 and 1.70 and a geometrical thickness e2 of between 5 and 50 nm; a high-index third layer (3), having a refractive index n3 of between 1.8 and 2.3 and a geometrical thickness e3 of at least 100 nm; a low-index fourth layer (4), having a refractive index n4 of between 1.30 and 1.70 and a geometrical thickness e4 of at least 80 nm. This antireflection coating can be used in solar modules.
