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.

Passive daytime radiative cooling (PDRC) has emerged as a promising, electricity-free approach that reflects sunlight while radiating heat through the atmospheric transparent window. However, design and optimization of PDRC materials remain challenging, requiring significant time resources for experimental numerical modeling efforts. In this work, we developed machine learning (ML)-driven to predict scattering efficiency in wavelength 0.3–2.5 μm, with aim eventually optimizing microstructural materials. By employing ML models such linear regression, neural networks, random forests, aimed optimize across different pore sizes mixed-pore-size configurations. As result, forest model demonstrated superior prediction performance minimal error, effectively capturing complex, non-linear interactions between material features. We also leveraged data transformation techniques one-hot encoding generative predictions The presented ML-driven platform serves valuable open resource researchers, facilitating rapid cost-effective accelerating development sustainable technologies.

Passive thermoelectric devices that utilize radiative cooling and solar heating have witnessed significant advancements in power generation. However, their applications promotions are limited due to the low unsustainable output. In this study, we propose a compact passive device (TED) consisting of generator (TEG) equipped with cooler (RCer) absorber (SAer) for 24-h electricity The RCer is made high-scattering porous cellulose film thickness 100 μm. It coated onto TEG's sky-facing terminal which serves as cold end. SAer an aluminum substrate black paint. attached opposite TEG hot By compactly integrating SAer, proposed TED can harvest energy from space continuous electric generation manageable implementations. Outdoor experiments shown during clear daytime, maximum temperature difference between ends reached 7.7 °C, average 2.8 °C. During nighttime, could reach 1.7 0.9 outputs daytime nighttime 351.6 mW·m−2 31.0 mW·m−2, respectively. This study introduces conceptual design lays foundation practical powering outdoor microdevices.
