Our paper "Hydrophobic Light-to-Heat Conversion Membranes with Self-Healing Ability for Interfacial Solar Heating​" was accepted in Advanced Materials. This paper reports a new concept of accepting and converting solar light to heat only at water-air interface to generate a precisely local heating of interfacial water to enhance water evaporation. A solar-driven and self-powered point-of-use freshwater production device was demonstrated as a proof-of-concept in the paper.
