A solar selective coating has been fabricated by capping black zinc oxide with a transparent zinc oxide heat mirror film. Deposition onto glass substrates was accomplished by reactive bias sputtering. The zinc oxide multilayer structure had a solar absorptance of 0.90 and an IR emittance of 0.26. Suggestions are made for significant improvement of solar selective performance.
