Recent developments of carbon-based solar absorbers in SSD are reviewed, including composites of carbon materials with other materials such as metal nanoparticles, semiconductors and biomass materials, their photothermal conversion mechanisms, light utilization efficiencies and salt resistance, and the processes of thermal transport and water transfer. The important roles of car-bon in SSD are highlighted, including increasing light absorption, improving photothermal conversion efficiency, and balancing wa-ter transfer and salt resistance. The key challenges of carbon-based materials in SSD applications are discussed.
