Five-layer coating system for e.g. glass substrates, achieving low reflectance and suitable for solar collection technology, includes metal oxide and chromium nitride layers

摘要

The first layer (1) located directly on the substrate (S), comprises chromium dioxide, and the fourth (4) is specularly-reflective, all in known construction. The second layer (2) on the first, is a metal oxide. The third layer (3) on the second is chromium nitride.
