From Materials to Devices: Rationally Designing Solar Steam System for Advanced Applications

Abstract Solar‐driven water vaporization for freshwater production attracts significant interest due to its potential for solving global water scarcity problems. In this review, the recent development of management strategies via diverse rational designs in terms of light, thermal, water, and anti‐salt fouling for enhancement of overall vaporization efficiency, is summarized. For device design, a host–guest concept is raised for clearly elaborating the detailed function and interaction between the solar–thermal material and the substrates. In addition, the rising technologies derived from solar vaporization, such as energy generation, photocatalysis, dehumidification, salt harvesting, sterilization, and biofuel production, are also highlighted. This review provides a new horizon toward the development of solar technologies and practical applications.
