Fundamentals of Energy Conversion Processes

A DFG Cluster of Excellence

About e-conversion

e-conversion is a Cluster of Excellence funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) with a focus on investigating fundamental mechanisms of energy conversion processes.

Today’s sustainable energy research gains momentum by targeting specific energy technologies and their related materials. The cluster e-conversion instead strives to establish a complementary paradigm that bridges major energy conversion strategies ranging from photovoltaics over (photo)electrocatalysis to batteries by focusing on the materials interfaces that underlie these functions. Critical bottlenecks like recombination and relaxation losses, overpotentials, and resistances presently arise due to insufficient control of microscopic excitation and energy conversion (e-conversion) processes at these interfaces. e-conversion therefore merges the powerful concepts of nanoscience and mechanistic energy research to create well-defined and tunable reference systems, and to establish fundamental understanding through their comprehensive (operando) characterization.
