A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement
Advanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination systems.
