Materials for Energy Conversion


Mission We strive to solve industry-relevant challenges for sustainable energy conversion and storage technologies through materials and device innovation.

Expertise Our laboratory possesses strong competencies in the synthesis and processing of functional electronic and ion conducting materials, the characterization of their structural, electronic, ionic and thermal transport properties, as well as their integration and performance assessment in operational devices.

Research Our research aims at developing fundamental knowledge through experiment and modeling enabling new materials and processes that improve device performance, cost, and reliability. We are currently working on the following application-driven topics: batteries, electrochemical production of synthetic fuels, waste heat recovery by thermoelectrics, and photovoltaics.
