Solar-driven interfacial evaporation (SDIE) is an emerging eco-friendly and low-carbon technology and has been widely studied in the field of photothermal applications in recent years. With the attention and development of SDIE in innovation fields, new strategies, structures, and typical materials are gradually being developed and applied. Therefore, it is important to report on these latest developments. Here, we provide a detailed review of advanced materials, structural strategies, and emerging applications in the field of SDIE. Advanced photothermal materials, such as biomass materials, hydrogels, metal-organic frameworks, and light-absorbing materials, have demonstrated significant desalination capability. Three-dimensional evaporators absorbing energy from the environment to enhance evaporation and salt resistance are described in detail. Furthermore, new strategies of integrated hydropower generation, evaporative/radiative cooling, atmospheric water harvesting, photocatalytic degradation, and heavy metal removal are highlighted. In addition, new concepts of soil remediation technologies covering saline soil remediation, automated soil irrigation, and soil fertility enhancement are reviewed in detail. Finally, the future challenges and perspectives of the SDIE technology for multidisciplinary applications are discussed and analyzed.

Global water scarcity demands next-generation desalination technologies that transcend the limitations of energy-intensive processes and salt accumulation. Herein, a groundbreaking interfacial solar steam generation system capable of simultaneous hypersaline desalination and ambient energy harvesting is introduced. Through hierarchical hydrogel architecture incorporating a central vertical channel and radial channels with gradient apertures, the design effectively decouples salt transport and water evaporation: solar-driven fluid convection directs water outward for evaporation, while inward salt migration prevents surface crystallization and redistributes excess heat.

Solar-driven hydrogen peroxide (HO) production offers a green and sustainable alternative to the energy-intensive anthraquinone process, utilizing water and oxygen as feedstock and solar energy as the sole input. Covalent organic frameworks (COFs), owing to their well-defined crystalline structures and tunable electronic properties, have emerged as a compelling platform for photocatalytic HO synthesis. However, the efficiency of HO photosynthesis remains limited by sluggish charge separation and rapid carrier recombination.

Owing to the crucial role in energy transformation for decarbonization, sustainable lithium (Li) supply has become growingly critical. Low-quality brines hold vast potential due to infinite reserves and diverse distribution but desire green and cost-effective extraction techniques against low Li concentrations and high magnesium-to-lithium ratios. Solar-driven direct lithium extraction (SDLE) systems combining conventional evaporation and DLE techniques can overcome the present challenges of Li extraction, promising to advance the exploitation of low-quality brines while simultaneously producing fresh water.

Sustainable water, energy and food (WEF) supplies are the bedrock upon which human society depends. Solar-driven interfacial evaporation, combined with electricity generation and cultivation, is a promising approach to mitigate the freshwater, energy and food crises. However, the performance of solar-driven systems decreases significantly during operation due to uncontrollable weather.
