[资源] 太阳能蒸汽 Solar water evaporation by black photothermal sheets

Solar energy-to-heat conversion for steam generation is an essential metrology for power generation, water
purification and desalination. Harvesting light energy and converting it to heat as terminal energy by black
photothermal sheets is a novel strategy to attain this goal. This technology rely on use of black nanomaterials as
light absorber to increase the absorption and conversion efficiency of solar energy. Fundamental understanding
of their structure-property has to be fully exploited for further developing efficient solar-to-heat systems. This
report summarizes physical understanding and experimental advances in development of black photothermal
sheets for solar water evaporation. We examine the popular photothermal systems with remarkable vapor
generation performance to identify the state-of-the-art of the device design. Three groups of the photothermal
sheet are discussed in terms of different light-harvesting materials, such as carbon-based sheets, plasmonic sheets
as well as semiconducting sheets. The physical difference of these novel devices with their steam releasing
property are also highlighted.
