Recent advances in solar‐driven interfacial evaporation (SDIE) have led to high evaporation rates that open promising avenues for practical utilization in freshwater production and industrial application for pollutant and nutrient concentration, and resource recovery. Breakthroughs in overcoming the theoretical limitation of 2D interfacial evaporation have allowed for developing systems with high evaporation rates. This study presents a comprehensive review of various evaporator designs that have achieved pure evaporation rates beyond 4 kg m−2 h−1, including structural and material designs allowing for rapid evaporation, passive 3D designs, and systems coupled with alternative energy sources of wind and joule heating. The operational mechanisms for each design are outlined together with discussion on the current benefits and areas for improvement. The overarching challenges encountered by SDIE concerning the feasibility of direct integration into contemporary practical settings are assessed, and issues relating to sustaining elevated evaporation rates under diverse environmental conditions are addressed.

Solar‐driven interfacial evaporation is a potential strategy to address freshwater scarcity. However, simultaneously achieving high evaporation performance and effective salt resistance remains a significant challenge. Herein, a triple‐layered aerogel‐based solar evaporator with low‐tortuosity pore structures (Tri‐ASEL) is constructed. Benefiting from the unique pore structures of Tri‐ASEL, it not only exhibits excellent water transport capacity, which is significantly increased by 237.5% compared to that of the aerogel‐based solar evaporator with uniform pore structures, but also effectively reduces the downward heat transfer owing to the low thermal conductivity of the top layer. Meanwhile, compared with the aerogel‐based solar evaporator with triple‐layered pore structures (Tri‐ASE), Tri‐ASEL can reduce the resistance of ion diffusion and shorten the diffusion pathways through the low‐tortuosity pore structures. Because of the effective coordination of the contradiction among the water transport, ion diffusion, and thermal insulation, Tri‐ASEL achieves a high evaporation rate of 2.803 kg m−2 h−1 and exhibits a remarkable evaporation efficiency of 97.95% under 1 sun. More importantly, it demonstrates excellent salt resistance and can operate stably in ultra‐high salinity brine (25 wt%) for more than 8 h without salt crystallization. This study provides a new approach for optimizing the structure design of evaporators.
