The article "Solar-driven interfacial evaporation: materials design and device assembly" by Satheesh Kumar Balu, Sijie Cheng, Sanjay S. Latthe, Ruimin Xing, and Shanhu Liu provides a comprehensive overview of solar-driven interfacial evaporation (SIE) technology, focusing on materials design and device assembly. SIE is an emerging technique that leverages solar energy to enhance water evaporation, addressing global water scarcity issues. The review highlights the importance of photothermal materials, such as carbon-based materials (graphene, carbon nanotubes), metal-based materials (gold, silver), metal oxide-based materials (titanium dioxide, zinc oxide), and polymers, in improving SIE efficiency. It also discusses advanced device configurations, including single-layer and bilayer structures, and innovative fabrication techniques like self-assembly, layer-by-layer deposition, electrospinning, and 3D printing. The article emphasizes the need for optimal solar absorption, minimizing heat loss, and enhancing vapor generation and transport to maximize SIE performance. Recent advancements in SIE, including the use of novel materials and structures, are discussed, along with challenges and future research directions. The authors aim to inspire further development of SIE technologies to contribute to sustainable water desalination and energy generation.The article "Solar-driven interfacial evaporation: materials design and device assembly" by Satheesh Kumar Balu, Sijie Cheng, Sanjay S.
