Sustainable technologies

How can physics contribute to a safe, climate-friendly and resource saving energy supply of the future? We are developing technologies to do this—from innovative solar materials to novel energy storage systems. 

A particular focus is on the conversion of sunlight into electricity: We are investigating materials and concepts for high-performance and environmentally friendly solar cells, especially perovskite tandem cells. We are focusing not only on achieving high efficiency but also on utilizing environmentally friendly, available, and energy-efficient materials. The goal is to ensure real sustainability, one that goes beyond only considering technical efficiency, also taking rebound effects into consideration. 

We are also studying the electrochemical conversion and storage of energy. Using high-resolution measuring methods—for example, electron microscopy—and theoretical models, we analyze how electrons and ions move in electrochemical systems, how interfaces change, and how the understanding gained can be used to develop long-lasting, safe, and efficient storage systems.

Our research aims at solutions that can be integrated into a circular economy due to an approach centered on material-oriented development, system efficiency, and a deep physical understanding of the underlying processes.
