Vapor condensation with daytime radiative cooling [PDF]
Proceedings of the National Academy of Sciences, 2021 Significance Traditionally, the cooling for passive vapor condensation is mainly provided by convection and conduction. However, these mechanisms do not work when the vapor temperature is near the ambient air temperature. At such temperatures, radiative condensation remains effective.

Accelerating vapor condensation with daytime radiative cooling [PDF]
New Concepts in Solar and Thermal Radiation Conversion II, 2019 Vapor condensation plays a crucial role in solar water-purification technologies. Conventional condensers in solar water-purification systems do not provide sufficient cooling power for vapor condensation, limiting the water production rate to $0.4 L m^{-2} hour^{-1}$.

Daytime radiative cooling with silica fiber network [PDF]
Solar Energy Materials and Solar Cells, 2020 Abstract Daytime radiative cooling under sunlight can be achieved by embedding micro-sized objects into a binder. In the present article, by carrying out a numerical study of daytime radiative cooling material design using statistical Monte Carlo method, we demonstrate that a silica (SiO2) fiber network can efficiently reflect sunlight via ...
