Emanuel Ronge

Emanuel Ronge is a researcher at Forschungszentrum Jülich's Institute of Energy and Climate Research, specializing in advanced materials for photoelectrochemical water splitting applications. His work focuses on developing stable semiconductor-based photocathodes for solar-driven hydrogen production.

Dr. Ronge's research interests center on photoelectrochemistry, materials science for renewable energy, and semiconductor physics. He investigates stability mechanisms of silicon photocathodes protected by ultrathin TiO₂ layers, employing transmission and scanning electron microscopy to study degradation processes. His expertise includes atomic layer deposition techniques for creating corrosion-protective coatings and optimizing interfaces between multi-junction solar cells and protective layers.

His publications demonstrate significant contributions to understanding the relationship between material properties and device performance in photoelectrochemical systems. Ronge's work has helped identify degradation mechanisms related to chlorine remnants in TiO₂ layers and has contributed to developing integrated devices achieving solar-to-hydrogen efficiencies up to 4.4% without external bias.
