Abstract
A selective absorber consisting of a number of thin layers on a supporting substrate, including (1) a carbonaceous layer, (2) a catalyst layer, and (3) a metallic infrared reflecting layer. The catalyst layer serving to catalyze the pyrolysis of a carbon containing gaseous compound or compounds to form the carbonaceous layer. Methods of production are described.
