TRANSPARENT SUBSTRATE COMPRISING AN ANTIREFLECTION COATING

摘要

The invention concerns a transparent substrate (6) comprising at least an antireflection coating, consisting of a stack (A) of thin films, having alternately high and low refractive indices. The stack successively comprises: a first film (1), with high refractive index n1 ranging between 1.8 and 2.3 and a geometric thickness e1 ranging between 5 and 50 nm; a second film (2) with low refractive index n2 ranging between 1.30 and 1.70 and a geometric thickness ranging between 5 and 50 nm; a third film (3) with high refractive index n3 ranging between 1.8 and 2.3 and a geometric thickness of at least 100 nm; a fourth film (4) with low refractive index n4 ranging between 1.30 and 1.70 and a geometric thickness e4 of at least 80 nm. Said antiglare coating can be used in solar cell modules.
