Abstract
The subject of the invention is a transparent substrate () 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 (), having a refractive index nof between 1.8 and 2.3 and a geometrical thickness eof between 5 and 50 nm, a low-index second layer (), having a refractive index nof between 1.30 and 1.70 and a geometrical thickness eof between 5 and 50 nm, a high-index third layer (), having a refractive index nof between 1.8 and 2.3 and a geometrical thickness eof at least 100 nm, and a low-index fourth layer (), having a refractive index nof between 1.30 and 1.70 and a geometrical thickness eof at least 80 nm. This antireflection coating can be used in solar modules.
