Micro–Nano Water Film Enabled High-Performance Interfacial Solar Evaporation

Abstract

Highlights Micro–nano water film enhanced interfacial solar evaporator enables a high evaporation rate of 2.18 kg m−2 h−1 under 1 sun. An outdoor device with an enhanced condensation design demonstrates a high water production rate of 15.9–19.4 kg kW−1 h−1 m−2. A multi-objective predictive model is established to assess outdoor water production performance.
