Superhydrophilic Coatings Keep Solar Cells in Peak Working Order . DRESDEN, Germany, Jan. 30, 2023 — Researchers at the Fraunhofer Institute for Organic Electronics, Electron Beam, and Plasma Technology FEP (Fraunhofer FEP) produced hydrophobic, or water-repelling, surfaces that become superhydrophilic, or superwetting, under ultraviolet (UV) light. For solar modules, the creation of a superhydrophilic surface will better protect panels and glass facades from expensive a...
