Abstract: Solar interfacial evaporation method is to use a specific structure to limit the energy in the light absorption layer, so that the water evaporates on the surface of the structure. Due to the simple structure, small space occupation, high energy utilization rate and low requirements for operating environment, solar interfacial evaporator has attracted wide attentions. Currently, researchers have conducted abundant researches on the solar interfacial evaporation method from the aspects of optical absorber materials, heat management, evaporator structure, etc. However, there are relatively few studies on the applications of solar interfacial evaporation method. Solar interfacial evaporation method due to its unique advantages, not only shows broad applications prospect in the field of seawater desalination, but also has great potential in many other fields. In this paper, the application fields of solar interfacial evaporation method are sorted out from the aspects of water resources management, energy supply and medical treatment. The potential applications of solar interfacial evaporation method are also discussed. It is of great significance to enrich the research scope of solar interfacial evaporation, promote the development of solar interfacial evaporation method at the application level, and explore the joint application of solar interfacial evaporation in many fields.
