Abstract

We discuss recent advances in both the fundamental science and technological application of radiative cooling. We will introduce a range of super-white paint-based strategies for daytime radiative cooling materials. We will next discuss a new domain of application for radiative cooling: vertical facades of buildings that experience asymmetric thermal radiative environments, highlighting the remarkable cooling benefits that infrared selective thermal emitters, including low-cost scalable ones made from existing polymers, can enable. Finally, we highlight new work on harnessing radiative cooling for water technologies, including passive freezing desalination as well as near-optimal condensation of dew through the development of multi-functional slippery hydrophilic radiative cooling materials.
