Solar Desalination Solar desalination offers a sustainable route to freshwater but is often hindered by low evaporation rates and salt fouling. In article number 2501360, Ji-Hyun Jang and co-workers demonstrated that La0.7Sr0.3MnO3 enables efficient photothermal conversion via intra-band trap states, achieving a high evaporation rate of 3.40 kg m−2 h under one sun. Additionally, its edge-directed salt management effectively prevents surface fouling.
