Abstract
AbstractHerein, an integrated solar‐thermal‐power protocol is presented at a micro‐nanoscopic level to maximize the energy utilization efficiency involving utilization period and utilization patterns, and the nexus of freshwater production and nanogeneration is realized. This sophisticated vaporization device is constructed with the merits of thermally confined evaporation space in favor of recycling latent heat of condensation and optimizing light absorption based on the local sunlight angle of incidence. Inspired by a bird's nest, Sb2WO6/D‐Fructose composites are prepared as photothermal absorbers to achieve a superior water evaporation rate of 2.78 kg m−2 h−1 in the Multi‐stage evaporator. In addition, a synergistic tandem photo thermal‐electric device with a combination of solar‐driven water evaporation and further waterflow‐driven hydrovoltaic generation, which can output a stable voltage of up to 360.8 mV with effective utilization of steam energy and a limited water source, is exploited. Such integrated configurations pave a pathway for clean water production and renewable power generation simultaneously toward energy issues.
