摘要：Interfacial solar-steam generation is a promising and cost-effective technology for both desalination and wastewater *** process uses a photothermal evaporator to absorb sunlight and convert it into heat for water *** solar-steam generation can be somewhat inefficient due to energy losses via conduction,convection and ***,efficient energy management is crucial for optimizing the performance of solar-steam ***,via elaborate design of the configuration of photothermal materials,as well as warm and cold evaporation surfaces,performance in solar evaporation was significantly *** was achieved via a simultaneous reduction in energy loss with a net increase in energy gain from the environment,and recycling of the latent heat released from vapor condensation,diffusive reflectance,thermal radiation and convection from the evaporation ***,by using the new strategy,an evaporation rate of 2.94 kg m^-2 h^-1,with a corresponding energy efficiency of solar-steam generation beyond theoretical limit was achieved.
