Glazing element used in heat absorbers or photovoltaic modules comprises a first light-permeable substrate arranged next to a second light-permeable substrate

摘要

Glazing element comprises a first light-permeable substrate (2) arranged next to a second light-permeable substrate (3). A reflection-reducing layer (9,9) is deposited on the substrate surfaces (5,6,7,8) using a PVD or CVD method. Hollow chambers are formed in the reflection-reducing layer.
