Abstract

Abstract: Solar vapor generation is a reliable, environmentally friendly, inexpensive technology making use of solar energy by photothermal conversion progress. Photothermal conversion, heat management, water transport and vapor escape are integrated and finely designed for interfacial solar vapor generation (ISVG). With the aid of microstructural photonics, material modification, thermal structure design, mechanical design, ISVG system can absorb salty, polluted bulk water or even vapor from atmosphere and evaporate it to produce fresh water, mineral salt, energy efficiently and fast. ISVG technology has aroused great interest among researchers and made substantial progress. The working mechanism and component materials of ISVG system are briefly introduced. Macro/microstructure design and optimization strategies of photothermal conversion, heat management, water transport, and vapor escape are summarized. The peripherals of ISVG are shown by introducing detailed applications. Finally, the conclusions and outlook of ISVG are summarized.
