Interfacial Solar Vapor Generation: A Multifunctional Platform for Sustainable Water Production and Energy Cogeneration

Abstract Freshwater scarcity and the global transition to renewable energy necessitate transformative solutions. Interfacial solar vapor generation (ISVG) has emerged as a pivotal technology, leveraging solar energy for efficient energy generation alongside desalination and freshwater production. This review comprehensively examines the coupling mechanism of ISVG‐enabled water‐electricity and water‐hydrogen cogeneration systems driven by photocatalysis and ISVG, as well as highlighting advancements in materials and system integration that enhance performance and resource efficiency.
