Colloidally deposited high-temperature solar selective surfaces.
Selective surfaces with high temperature stability have been produced by colloidal deposition of carbon and silica onto copper-coated substrates. The surface of best performance had a solar absorptance of 0.87 and a room temperature emittance of 0.03. After heat treatment at 600 degrees C in vacuum for 200 h the surface properties remained unchanged.
