Advanced solar selective coatings
Advanced solar selective coatings employ two patent technologies :
(1) double cermet film structure with the highest photothermal efficiency
(2) metal-Aluminum nitride cermet (M-AlN) materials deposited by a novel sputtering technology.
The typical film structure of M-AlN cermet selective surfaces
