Abstract
Solar absorbing Black Chrome coating have been exposed to high temperatures (350-400°C) under high solar fluxes (0.4 to 2.0 MW/mL) to test for their stability under actual operating conditions. Field tests at the White Snds Solar Furnace have shown higher stability than expected from oven tested samples. Laboratory studies utilizing spectrally selective concentrated solar simulated radiation have indicated that the cause of the higher stability under solar irradiation is photo-stimulated desorption of oxygen bearing species at the absorber surface and resultant reduced oxidation of the absorber.
