Sacrificing Energy for Mass Transfer to Boost Solar Steam Generation

Vapor accumulation often limits the performance of passive interfacial solar evaporation. Inspired by the Dyson sphere concept, Xu, Yang, and co‐workers designed a perforated‐shell evaporator with an internal non‐evaporating core that diverts incident sunlight to drive self‐generated internal convection for vapor removal. This strategy provides a versatile pathway for enhancing interfacial mass transfer in sustainable solar to water technologies.
