Abstract: Advanced photothermal structures with self-salt cleaning mechanisms are needed to reduce salt accumulation and solar steam generation efficiency loss. Traditional solar evaporators fail to maintain efficient evaporation and long-term salt rejection due to increasing salinity. A salinity gradient fabric evaporator with a 70° inclination angle is constructed to tackle this dilemma. In contrast to traditional designs, the auxiliary salinity gradient and Joule heating enhance ion circulation and reduce salinity buildup within high-concentration salt removal operations. This results in continuous salt rejection and better energy utilization through moderate Marangoni flow. The evaporator endows an accelerated evaporation rate (2.08 kg m−2 h−1) under one sun irradiation, and exceptionally enhanced up to 8.73 kg m−2 h−1 under joule heating effect (4.5 V), with superior salt resistance (09 days of desalination in 10 wt% brine), are simultaneously achieved through optimized salinity gradient construction. A notable water evaporation rate of 39.8 % is achieved during high-salinity outdoor desalination, demonstrating its effective purification capability. This study offers insights into the design of salinity gradient evaporators aimed at enhancing efficient and sustainable clean water production.
