Water and electricity scarcity are global challenges. Utilizing moisture and sunlight for water and power generation is a sustainable approach. This work demonstrates a moisture-induced energy harvesting strategy for efficient atmospheric water harvesting and 24-hour thermoelectric power generation. The results show promising potential for sustainable water production and power generation.
Water and electricity scarcity are two global challenges, especially in arid and remote areas. Harnessing ubiquitous moisture and sunlight for water and power generation is a sustainable route to address these challenges. Herein, we report a moisture-induced energy harvesting strategy to realize efficient sorption-based atmospheric water harvesting (SAWH) and 24-hour thermoelectric power generation (TEPG) by synergistically utilizing moisture-induced sorption/desorption heats of SAWH, solar energy in the daytime and radiative cooling in the nighttime. Notably, the synergistic effects significantly improve all-day thermoelectric power density (similar to 346%) and accelerate atmospheric water harvesting compared with conventional designs. We further demonstrate moisture-induced energy harvesting for a hybrid SAWH-TEPG device, exhibiting high water production of 750 g m(-2), together with impressive thermoelectric power density up to 685 mW m(-2) in the daytime and 21 mW m(-2) in the nighttime. Our work provides a promising approach to realizing sustainable water production and power generation at anytime and anywhere.
