摘要

Efficient solar vapor generation has been attracting a lot of attention for its potential in various applications,such as desalination,sterilization and chemical purification with a minimal carbon footprint.Tremendous progress has been achieved with materials designs for photon [1-3]and thermal management [4-6].However,with those improvements,losses related to convection and conduction start to dominate.For this reason,it becomes essential to minimize losses related to radiation,convection and conduction simultaneously for optimal solar steam performance and widespread application.So far,high solar-to-heat conversion efficiency (～80％) can only be achieved by using complicated structures [1].
