Sustainable Solar Evaporation from Solute Surface via Energy Downconversion.

ABSTRACT: Solar-powered interfacial evaporation, a cost-effective and ecofriendly way to obtain freshwater from contaminated water, provides a promising path to ease the global water crisis. However, solute accumulation has severely impacted efficient light-to-heat-to-vapor generation in conventional solar evaporators. Here, it is demonstrated that an interfacial solar thermal photo-vapor generator is an efficient light-to-heat photo-vapor generator that can evaporate water stably in the presence of solute accumulation. An energy downconversion strategy which shifts sunlight energy from visible-near infrared to mid infrared-far infrared bands turns water from transparent to its own absorber, thus changing the fixed evaporation surface (black absorber) in a traditional solar evaporator to a dynamic f
