Abstract Maintaining a match between input solar energy and required by water supply management is key to achieving efficient interfacial solar‐driven evaporation (ISDE). In practice, the radiation flux constantly changing throughout day, so keeping dynamic water‐energy‐balance of ISDE big challenge. Herein, photothermal diode (WD) evaporator concept proposed an integrated hydrophilic/hydrophobic Janus absorber overcome issue. Due unique unidirectional transport properties induced asymmetric wettability, self‐adaptive balance uptake established, thus realizing matching utilization maximization. The experimental simulation results exhibit that with increase sunlight intensity, speed significantly accelerated due self‐regulation on replenishment. Therefore, excellent rate up 2.14 kg m –2 h –1 high efficiency 93.7% under 1 sun illumination achieved. This engineering wettability provides novel strategy extends path for designing systems diverse properties, which shows great potential in different environmental conditions.
