This project aims to develop a multi-functional solar-thermal desalination device to simultaneously produce clean water and electricity. Interfacial solar evaporation-based desalination technology has the unique advantage of using solar light as the sole energy source for affordable clean water production. However, its absolute evaporation rate is still too low for practical application and all of the latent heat released from vapor condensation during desalination is wasted. Solving these two critical issues by the study of energy nexus, design and fabrication of advanced photothermal materials and desalination devices could accelerate practical adoption of this technology and benefit millions of people who desperately need clean water.

该项目旨在开发一种多功能太阳能热脱盐装置，同时生产清洁水和电力。基于界面太阳能蒸发的海水淡化技术具有独特的优势，即利用太阳光作为唯一的能源，生产负担得起的清洁水。然而，其绝对蒸发速率对于实际应用来说仍然太低，并且在脱盐期间从蒸汽冷凝释放的所有潜热都被浪费。通过研究能源关系、设计和制造先进的光热材料和海水淡化设备来解决这两个关键问题，可以加速这项技术的实际应用，并使数百万迫切需要清洁水的人受益。
