“…[30][31][32][33][34] Phase-change materials (PCMs) such as paraffin wax, fatty acids, esters, glycols, and salt hydrates are widely used in a variety of technologies to smooth solar fluctuations in moderate temperature conditions via a passive energy storage-release process. [35][36][37] Ideally, integrating PCMs into conventional SSG materials should be a facile way to realize mitigation of solar fluctuations. But different from conventional solar water heating system, [38] or other solar-driven, water-free technologies such as solar photovoltaic (PV), [39] water suffuses in the entire porous structure of SSG material and fast transport from bulk to evaporation surface by capillary pumping, diffusion, and pulling force during whole working time.…”

Solar‐driven steam generation by heat localization has proven to be one of the most promising technologies for broad water‐related applications to relieve global water shortage and pollution due to the excellent interfacial water evaporation ability demonstrated both experimentally and theoretically. However, a constant 1 sun is barely available in practical, fluctuations on solar energy intermittently invalidate conventional solar evaporator, leave a challenge on sustaining efficient thermal evaporation. Herein, we report a mitigating‐solar‐fluctuation hybrid gel material (MHG) with chemical integrating of phase change material to achieve efficient steam generation under solar fluctuations. By storing solar energy when it is surplus and providing thermal energy to sustain evaporation when it is insufficient, the MHGs solar evaporator under solar fluctuations achieves optimized water evaporation rate of 1.7±0.02 kg m‐2 h‐1 for the high period of 0.8 sun and 1.3±0.06 kg m‐2 h‐1 for the low period of 0.5 sun. The MHGs also exhibits outstanding solar desalination performance with good stability, and demonstrates an effective brine desalination during round‐the‐clock desalination process with an average high evaporation rate of 1.24 kg m‐2 h‐1 d‐1. This new material design provides a feasible strategy for solar evaporator to mitigate damage from solar fluctuations.This article is protected by copyright. All rights reserved.
