Abstract: A translucent or transparent film or sheet device shows angular-independent IR reflectance, which comprises a substrate (1) covered with a layer of a dielectric high refractive index material (4) containing a thin metallic layer (3) embedded in said material, and a further layer (5) of translucent or transparent material covering said layer (4) of dielectric high refractive index material, characterized in that the embedded metal layer (3) is periodically interrupted with a periodicity of 50 to 800 nm such that metal covers at least 70% of the substrate area. The device may advantageously be integrated into a window, a glass facade element or especially onto a photovoltaic (PV) device, where it reduces the fraction of IR radiation passing into the building, or reduces heat take-up and thus lowers the operating temperature and improves the efficiency of the PV cell.

Abstract: A translucent construction element comprising a layer of translucent substrate, which contains a surface structured with nanoplanes of inclined angle relative to the substrate plane, and coated with an interrupted metallic layer covering at least a part of said nanoplanes, is characterized by a high density of interruptions in the metallic layer of low thickness; the periodicity of interruptions in the metallic layer generally is from the range 50 to 1000 nm and the thickness of the metallic layer typically is from the range 1 to 50 nm. The construction element may be integrated, for example, into windows, plastic films or sheets or glazings, especially for the purpose of light management.
