Enabling Self‐Adaptive Water‐Energy‐Balance of Photothermal Water Diode Evaporator: Dynamically Maximizing Energy Utilization Under the Ever‐Changing Sunlight
Shaanxi University of Science and Technology
Abstract
Abstract Maintaining a match between input solar energy and required energy by water supply management is key to achieving efficient interfacial solar‐driven evaporation (ISDE). In practice, the solar radiation flux is constantly changing throughout the day, so keeping a dynamic water‐energy‐balance of ISDE is a big challenge. Herein, a photothermal water diode (WD) evaporator concept is proposed by an integrated hydrophilic/hydrophobic Janus absorber to overcome the issue. Due to the unique unidirectional water transport properties induced by asymmetric wettability, a self‐adaptive balance between photothermal energy input and water uptake is established, thus realizing the energy matching and utilization…
