The visible light-transparent and radiative-cooling multilayer film adopts a new film layer arrangement, so that the multilayer film has an extremely high visible light transmittance while achieving radiative cooling. Among others, the multilayer film is composed of two materials having high visible light-transmittance. Since there is a difference between dielectric constants of the two materials, a resonant cavity or resonant cavities may be formed among material layers. The resonant cavity may enhance the electric field therein, thereby increasing the radiance of the structure greatly.
