 Solar-driven interfacial evaporation has been rapidly developed over the last few years due to its potential for low-cost water desalination. Photothermal materials and structures have enabled high conversion efficiencies of up to 100%, with some achieving beyond the theoretical limit. This paper reviews the latest advances in the field, including the design principles for enhancing evaporation performance and current strategies for salt rejection. Additionally, the paper discusses the opportunities and challenges for future research in this area.
