Performance analysis of a contactless nanostructure in solar-powered desalination system.

To address the water scarcity problem, solar desalination by using solar still can be one feasible solution to purify the water. Researchers recently developed thermal absorption materials fully and partially submerged in water and floating. These thermal absorption materials transfer their absorbed solar energy to water through thermal conduction.

Historic review and recent progress in internal design modification in solar stills.

Solar still, which uses solar renewable energy sources, especially solar energy, to produce pure water, is a promising technology as it is abundantly available and eco-friendly. Researchers have innovated in internal and external designs to enhance distillate productivity in solar desalination systems. The present review paper discusses the major internal modifications done in history and recent past to enhance the distillate output.
