Ultrahigh-efficiency desalination via a thermally-localized multistage solar still
Feb 7, 2020
Congratulations to Zhenyuan Xu, Lenan Zhang, Lin Zhao, Bikram Bhatia, Kyle Wilke, Youngsup Song and their collaborators in China for their recent work on ultrahigh-efficiency solar-powered water desalination which was featured on MIT News. This work demonstrated a record-high solar-to-vapor conversion efficiency of 385% with a production rate of 5.78 L m-2h-2 using a low-cost and free-of-salt accumulation multistage architecture. This work elucidates the fundamental limit of the solar-to-vapor conversion process and provides useful design guideline for existing passive solar thermal desalination technologies.
