Bioinspired Switchable Passive Daytime Radiative Cooling Coatings

ACS Applied Materials & Interfaces, 2023
Passive daytime radiative cooling (PDRC) relies on simultaneous reflection of sunlight and radiation toward cold outer space. Current designs of PDRC coatings have demonstrated potential as eco-friendly alternatives to traditional electrical air conditioning (AC).

Color-preserving daytime radiative cooling

Applied Physics Letters, 2013
We introduce a general approach to radiatively lower the temperature of a structure, while preserving its color under sunlight. The cooling effect persists in the presence of considerable convective and conductive heat exchange and for different solar absorptances.

Superhydrophobic porous film for daytime radiative cooling

Applied Materials Today, 2021
Abstract Passive daytime radiative cooling (PDRC) offers a sustainable way without additional energy input to cool objects by simultaneously reflecting sunlight and radiating heat through mid-infrared wavelengths. However, PDRC materials are easily contaminated by rain water, settled dust, microorganisms etc., which cause degradation in the cooling ...

Passive sub-ambient daytime radiative cooling

OSA Advanced Photonics Congress (AP) 2019 (IPR, Networks, NOMA, SPPCom, PVLED), 2019
Passive daytime radiative cooling approaches primarily rely on spectrally selective surfaces whose performance is limited by heat gain due to solar absorption and parasitic conduction and convection. We propose and experimentally demonstrate a directional approach to perfectly reject direct solar radiation and an optically-selective thermally ...

Multifunctional Daytime Radiative Cooling Devices with Simultaneous Light-Emitting and Radiative Cooling Functional Layers

ACS Applied Materials & Interfaces, 2020
In this study, multifunctional light-emitting and passive radiative cooling (LEPC) materials and devices are designed by embedding chemically designed perovskite nanocrystals (NCs) into the radiative polymer layer. Lead halide perovskite NCs are chosen as the light-emitting material, owing to their high photon radiation rate and low phonon generation ...

Emerging Materials and Strategies for Passive Daytime Radiative Cooling

Small, 2023
AbstractIn recent decades, the growing demands for energy saving and accompanying heat mitigation concerns, together with the vital goal for carbon neutrality, have drawn human attention to the zero‐energy‐consumption cooling technique. Recent breakthroughs in passive daytime radiative cooling (PDRC) might be a potent approach to combat the energy ...
