Passive radiative cooling (PRC) is a zero-energy cooling technology, which can replace air conditioning in buildings and be used for thermal management of solar cells. The PRC emits heat as form of electromagnetic wave to outer space (~3 K) using atmospheric window in wavelength region of 8–13 μm. So, many researchers have investigated micro/nano materials such as metamaterials, photonic structures to enhance long-wavelength infrared (LWIR) emissivity. Moreover, solar reflection is important parameter to reduce absorption of solar energy, resulting effective radiative cooling. In this study, polymer film with hollow SiO2 microspheres has investigated to improve the solar reflection. The PRC film exhibits efficient cooling performance and excellent applicapability. |
