NOVELTY - A hybrid multilayer solar selective coating comprises tandem stack of layers containing interlayer of chromium/titanium, first absorber layer of aluminum-titanium nitride (AlTiN), second absorber layer of aluminum-titanium oxynitride (AlTiON), antireflection layer of aluminum-titanium oxide (AlTiO) and barrier layer of organically modified silica (ormosil), where the coating exhibits thermal resistance of 1-500 degrees C in air and of 1-600 degrees C in vacuum with solar selectivity ratio of 5-9.    USE - As hybrid multilayer solar selective coating is useful for solar thermal power generation (claimed).    ADVANTAGE - The hybrid multilayer solar selective coating provides higher solar selectivity ratio for effectively harnessing solar energy. The coating is stable under UV irradiation, external environment and thermal shock; and can be prepared by environment friendly method. The hybrid multilayer solar selective coating retains its structural composition and optical properties when annealed at high temperature and is stable 1-500 degrees C in air and 1-600 degrees C in vacuum under cyclic heating conditions. The hybrid multilayer solar selective absorber coating has high oxidation resistance, stable microstructure, high adherence and graded composition particularly suitable for applications in concentrating collectors like evacuated receiver tubes and Fresnel receiver tubes useful for solar steam generation. The coating has enhanced absorptance of greater than 0.95 and reduced emittance of less than 0.11.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of hybrid multilayer solar selective coating involving metallographically polishing and chemically cleaning of substrate in an ultrasonic agitator in acetone, absolute alcohol and trichloroethylene; depositing interlayer either by sputtering or electroplating; depositing solar absorber layers consisting of AlTiN, AlTiON and AlTiO using four-cathode reactive pulsed direct current unbalanced magnetron sputtering system; depositing ormosil layer by dip-coating to obtain hybrid multilayer solar selective coating.
