Solar interface evaporation (SIE) is a process of concentrating solar energy at the "air water" interface for heating, efficient gas production and seawater desalination. This method can effectively solve the problems of shortage of fresh water resources and low energy conversion efficiency. With the rapid development of photothermal materials and integrated systems, the function of interface evaporator is continuously optimized, which promotes the technical breakthrough of this method in the fields of water treatment, steam sterilization, enrichment of scarce resources and cogeneration power generation. Based on the previous research, combined with the latest research progress of SIE collaborative power generation, this paper combs the mechanism of SIE collaborative power generation, analyzes the design points of SIE collaborative power generation device, summarizes the practical application status of SIE collaborative power generation, and looks forward to its future development and challenges.
