Colored passive daytime radiative cooling coatings based on dielectric and plasmonic spheres
Abstract
A simple method is designed to create bilayer-colored PDRC coatings. R¯solar and ɛ¯LWIR of the white PDRC coating can be 0.94 and 0.93 at 300 μm. R¯solar of colored coatings can be 0.859 (with Au layer) and 0.822 (with Ag layer). Colored coatings show better PDRC performance than commercial white coatings.
