Passive sub-ambient daytime radiative cooling
OSA Advanced Photonics Congress (AP) 2019 (IPR, Networks, NOMA, SPPCom, PVLED), 2019Passive 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 ...

Emerging Materials and Strategies for Passive Daytime Radiative Cooling
Small, 2023AbstractIn 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 ...

Radiative Passive Cooling for Concentrated Photovoltaics
2019Photovoltaic (PV) cells have become an increasingly ubiquitous technology; however, concentrating photovoltaics (CPV), despite their higher theoretical efficiencies and lower costs, have seen much more limited adoption. Recent literature indicates that thermal management is a key challenge in CPV systems.

4A zeolite based daytime passive radiative cooling material
Infrared Physics & Technology, 2020Abstract Materials used for radiative cooling usually have high spectral reflectivity in the solar radiation band (0.3–2.5 µm) and high spectral absorptivity (or emissivity) in the infrared band (2.5–25 µm), particularly in the atmospheric window (8–14 µm). In this work, 4A zeolite was first used as a functional material for radiative cooling.

Biomimetic Alumina Film for Passive Daytime Radiative Cooling
ACS Applied Materials & InterfacesPassive daytime radiative cooling is receiving more and more attention as a cooling method that does not consume energy to cool objects. However, most radiative cooling materials require the mixing of multiple particles, which increases the manufacturing process requirements.

Designing the Future of Cooling: Superhydrophobic Passive Daytime Radiative Cooling Systems
ACS Applied Materials & InterfacesPassive daytime radiative cooling (PDRC) is a sustainable technology that reduces temperature by utilizing materials with high solar reflectance and thermal emittance to provide cooling without electricity. However, its performance is often compromised by dust and environmental contamination, with even minimal dust deposition (0.1 mg/cm2) reducing ...
