Abstract (en)

[origin: WO2007017504A1] The invention relates to an antireflection coating, particularly for solar cells, and to a method for producing this coating. An inventive antireflection coating (4) comprises at least one antireflection inner layer (6) made of porous silicon and comprises an outer layer (8) made of silicon oxynitride, which is essentially non-porous, essentially free from foreign species and which is formed on the inner layer.
