A nickel black solar selective coating, which is based on rich oxide-nickel metallic matrix deposited on nickel foil, was deposited by sputter ion plating in a reactive atmosphere. The optical properties of the nickel cermet are evaluated experimentally. A theoretical model of the proposed structure yields comparable but not identical results. The average value of the near normal hemispherical total solar absorptance as averaged over the air mass 2 solar spectrum is 0.95 ± 0.003. The near normal total thermal emittance, however, is 0.083 ± 0.005. The characteristics and stability of the coatings are also examined.
