Solar spectral selective coatings are classified into transparent films for energy efficiency windows of green buildings and transportations and absorbing coatings for solar thermal collectors.Solar spectral selective transparent films include 1)low emissivity transparent conductive thin films with typical examples of indium tin oxide(ITO),aluminum doped zinc oxide(ZAO)and single/double/triple silver layer based low emissivity multilayers;2)electrochromic multilayer smart windows with typical materials of WO3 and NiOx together with some Li+ or H+ ion conductors;3)thermochromic films typically VO2 doped by tungsten.These solar spectral selective transparent films are all applied for high energy efficiency windows to control solar and thermal radiation in or out of buildings.Solar spectral selective absorbing coatings are optically designed and optimized metal/ceramic gradient mixed multilayers.Materials are different for low,medium and high temperature applications.Special solar spectral selective absorbing coatings have been developed for building integrated solar thermal collections.
