COATINGS FOR OPTICAL COMPONENTS OF SOLAR ENERGY SYSTEMS

摘要

The present application is directed to a method of providing a coating to a surface of an optical element of a solar energy conversion system. The method comprises coating the surface of the optical element with an aqueous coating composition comprising water and silica nanoparticles dispersed in the water; and drying the coating composition to form a nanoparticle coating. The silica nanoparticles comprise a polymer core surrounded by a shell comprising nonporous silica particles disposed on the polymer core.
