A The digital photo of the continuous SAWH device. 1-support frame, 2-PV panel, 3-water collector, 4-shading panel, 5-shading cotton. Scale length: 5 cm. B The temperature of the sorbent and condenser outer surface after reaching the thermal equilibrium during the water production tests under different solar intensities. Error bar: standard deviation (SD). C The mass changes of the collected water under different solar irradiation intensities over 8-hour indoor tests. D The mass changes of the collected water with different cycle times under 4 suns over 8-hour indoor tests. E The temperature evolutions of different positions of the continuous SAWH device with a cycle time of 30 minutes under 4 suns during the 8-hour indoor test. F and G The simulation results of the water desorption-condensation processes. The temperature (F) and water vapor partial pressure (G) distributions in the device. H The water yield and water production rate of the continuous SAWH device under 4 suns over seven-day cycles. I Water collection performance comparison of our work and other solar-driven SAWH devices6,7,15,24,25,52,53,54.
