Abstract The unsustainable nature of energy‐intensive and environmentally unfriendly traditional air conditioning systems, compacted with recent climate change effects, show an urgent need for more sustainable efficient thermoregulation solutions. Innovations in passive daytime radiative coolers (PDRCs) selective solar absorbers (SSAs), which utilize natural resources, the “cold” outer space “hot” sun from sky, offer friendly cost‐effective alternative. However, various factors significantly impede commercial viability these technologies, such as lack emphasis on advancements practical application, challenge reversible functionality between PDRCs SSAs, inconsistent performance evaluation, absence effective mass production strategies. Here current challenges future development trends PDRC SSA‐aided innovation are discussed. Specifically, opportunities relating to application conditions, evaluation parameter standardization, strategies considered large‐scale production, all critical realizing full potential SSAs.

Solar evaporation attracted lots of attention due to its environment-friendly and high efficiency, which is a potential approach collecting fresh water. Many efforts have been made improve the rate in open space. While actual water collection far less than rate, especially passive collection, limiting practical scalable applications. In this review, we focus on freshwater based solar evaporation. Firstly, heat mass transfer behaviors side were summarized performance, including processes thermal radiation, convection, conduction; supply, enthalpy, salt rejection. Sequentially, subcooling, wettability, geometry condensation discussed should be designed collaboratively with confined Finally, recovery electricity generation beyond also introduced, some challenges still need further for applications, integrated system, long-term issues.

Passive cooling technologies have shown great interest recently due to their free electricity, especially for radiative (RC), and evaporation (EC). While single-mode passive is often limited by environmental conditions, such as sunlight, clouds, humidity, resulting in a performance. To address these issues, an adhesive hydrogel paint designed heat dissipation the daytime or high workload via coupled (REC), which also can realize water self-replenishment at night low RC-assisted adsorption moisture capture. Solar reflectance R¯solar${{\bar{R}}_{{\mathrm{solar}}}}$ = 0.91 thermal emittance ε¯LWIR${{\bar{\varepsilon }}_{{\mathrm{LWIR}}}}$ 0.94 are obtained RC. Excellent performance be achieved painting it on 3D W-shaped substrate. Compared with flat RC paint, REC W-shape substrate achieves temperature drop of 5.4 °C heating density 100 W m-2, further increased 11.4 400 m-2 multi-passive strategies. This structural material design provides potential outdoor dissipation.

Abstract Hygroscopic hydrogel is a promising evaporative-cooling material for high-power passive daytime cooling with water self-regeneration. However, undesired solar and environmental heating makes it challenge to maintain sub-ambient cooling. While different strategies have been developed mitigate heat gains, they inevitably sacrifice the evaporation regeneration due highly coupled thermal vapor transport. Here, an anisotropic synergistically performed insulation-radiation-evaporation (ASPIRE) cooler by leveraging dual-alignment structure both internal external coordinated The ASPIRE achieves impressive average temperature of ~ 8.2 °C remarkable peak power 311 W m −2 under direct sunlight. Further examining mechanism reveals that reduces gains without comprising evaporation. Moreover, self-sustained multi-day possible self-regeneration at night clear cloudy days. synergistic design provides new insights toward high-power, sustainable, all-weather applications.
