Optically effective layer system, useful as solar absorber layer system, comprises substrate, functional layer assembly, and assembly comprising cover layer made of titanium, oxygen, silicon and oxygen-containing material

摘要

The optically effective layer system comprises a substrate (S), a functional layer assembly, and an assembly comprising a cover layer (DS', DS'') made of dielectric, silicon and oxygen-containing material. The cover layer comprises titanium, oxygen, carbon and optionally hydrogen as essential components. The functional layer assembly comprises an absorber layer and a metallic reflection layer (RS). The cover layer assembly further comprises a transparent layer having a low refractive index of less than 1.6 at a wavelength of 550 nm.

The cover layer assembly further comprises a transparent layer having a low refractive index of less than 1.6 at a wavelength of 550 nm, and a transparent layer that is disposed above the low refractive index transparent layer and has a refractive index of greater than 1.9 at a wavelength of 550 nm. An independent claim is included for a process for producing an optically effective layer system.
