Patent number: 11754352Abstract: The present disclosure provides a visible light-transparent and radiative-cooling multilayer film, including N layers of films which have different thicknesses and are arranged alternately. 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. The present disclosure has the advantages of simple structure, easy to process, good cooling effect, high visible light transmittance and low cost.Type: GrantFiled: July 16, 2018Date of Patent: September 12, 2023Assignee: The Institute of Optics and Electronics, The Chinese Academy of SciencesInventors: Xiangang Luo, Xiaoliang Ma, Mingbo Pu, Xiong Li, Yinghui Guo
