Alternative water resources (seawater, brackish water, atmospheric sewage, etc.) can be converted into clean freshwater via high-efficiency, energy-saving, and cost-effective methods to cope with the global crisis. Herein, we provide a comprehensive systematic overview of various solar-powered technologies for alternative utilization (i.e., "sunlight-energy-water nexus"), including solar-thermal interface desalination (STID), membrane (STMD), solar-driven electrochemical (SED), harvesting (ST-AWH). Three strategies have been proposed improving evaporation rate STID systems above theoretical limit designing all-weather or all-day operating by analyzing energy transfer condensation processes caused conversion.

Abstract Solar‐driven interfacial desalination (SDID), which is based on localized heating and evaporation, provides an opportunity for developing environmentally friendly cost‐effective seawater thermal desalination. However, rapidly generated steam may cause salt to accumulate the evaporator's surface block channel of evaporation. Salt accumulation inevitably reduces light absorption service period solar absorber, resulting in a significant decrease evaporation efficiency over time. makes it difficult produce SDID devices with high energy long‐term stability large‐scale use remote poverty‐stricken areas. Therefore, exploration novel effective strategies addressing through both material design structural engineering has attracted more attention recent years. This review presents overview state‐of‐the‐art advancements salt‐resistant photothermal discusses critical issues achieving mitigation SDID, focusing classification configurations, basic mechanism mitigation, architectural materials. Finally, important challenges prospects are discussed providing meaningful roadmap efficient SDID.

The main challenges of a solar steam generation device based on biomass materials are complicated processing techniques and relatively low efficiency. To solve these problems, we reported simple immersion treatment method by depositing polydopamine (PDA) silver nanoparticles (AgNPs) natural wood to prepare novel interface evaporation device. Ag-PDA@wood exhibits unique bilayer structure. absorbance the top light absorption layer is higher than 96% in wide wavelength range (300–2500 nm). Owing synergistic photothermal effect between PDA AgNPs, has ultrafast solar–thermal response (a temperature increase 42.5 °C within 5 min under 1 sun), more heat located at (the surface 45.1 °C). bottom with thermal conductivity provides sufficient water supply reduces bulk loss. A high rate 1.58 kg m–2 h–1 achieved using sun (1 kW m–2).
