Abstract Photothermal conversion, heat localization and water supply are the keys to achieving efficient solar‐driven interfacial evaporation. However, effective coupling between three aspects at air/liquid interface remains challenging. Herein, Au@Ag‐Pd trimetallic nanostructure/polystyrene (PS) microsphere Janus structures designed as solar absorber thermal insulator. The deposited on a layer act 2D evaporator. PS localizes micrometer scale enhances plasmonic absorption of nanocrystals supported microsphere. Meanwhile, divide surface into multiple regions with sub‐micrometer depths, lowering evaporation enthalpy. Owing synergic effects these components, evaporator realizes solar‐to‐vapor conversion efficiency 99.1% an rate 3.04 kg m −2 h −1 in pure under 1 sun illumination. can last for over 40 h. Furthermore, shows high‐performance seawater desalination salt removal ratios near 100%. This study brings new insights controlling thermodynamics kinetics. nano‐micro structure design be extended other systems various solar‐thermal applications.

Interfacial solar‐driven water evaporation has shown promising prospects in desalination technology. However, the lower photothermal conversion efficiency caused by intermittent nature of sunlight and salt accumulation remains a significant challenge for continuous desalination. Herein, hierarchical design interfacial solar is reported, which realizes enhanced conversion, waste heat storage/release, effective thermal management The evaporator composed worm‐like SrCoO 3 perovskite oxide anchored on super hydrophilic polyurethane (PU) foam succeeded situ polymerization conducting polypyrrole (SrCoO @PPy). energy storage system introduced within matrix paraffin block followed tongue‐and‐groove structure convective transportation, recovery unit largely reduces losses. possesses excellent rates (2.13 kg m −2 h −1 ) along with 93% solar‐to‐vapor under 1 kw irradiation owing to its minimum equivalent enthalpy (0.85 as compared conventional evaporators. More importantly, state‐of‐the‐art experimental investigations validate recovery/release salt‐resistant capability evaporators optimized computational fluid dynamic simulation. This study breaks evaporation's limitations demonstrates stable sunlight.

Broadband Solar Metamaterial Absorbers Empowered by Transformer‐Based Deep Learning

Advanced Science, Год журнала: 2023, Номер 10(13)

Опубликована: Фев. 28, 2023

The research of metamaterial shows great potential in the field solar energy harvesting. In past decade, design broadband absorber (SMA) has attracted a surge interest. conventional typically requires brute-force optimizations with huge sampling space structure parameters. Very recently, deep learning (DL) provided promising way design, but its application on SMA development is barely reported due to complicated features spectrum. Here, this work develops DL model based spectrum transformer (MST) for powerful high-performance SMAs. MST divides optical into N patches, which overcomes severe problem overfitting traditional and boosts capability significantly. A flexible tool free customer definition developed facilitate real-time on-demand metamaterials various functions. scheme applied fabrication SMAs graded-refractive-index nanostructures. They demonstrate high average absorptance 94% broad exhibit exceptional advantages over many state-of-the-art counterparts. outdoor testing implies high-efficiency collection about 1061 kW h m-2 from radiation annually. This paves rapid smart SMA, will also provide developing other metadevices.
