The Professur für Röntgenspektroskopie at the Department of Chemistry and Pharmacy at FAU was installed in 2018 in the framework of a collaboration with the Helmholtz Zentrum Berlin für Materialien und Energie GmbH (HZB) and the Forschungszentrum Jülich GmbH.

Simultaneously, Prof. Bär also heads the Research Department „X-ray spectroscopy at interfaces of thin films“ at the Helmholtz-Institute Erlangen-Nürnberg for Renewable Energy (HI ERN) located on the FAU campus. Within his HI ERN activities, Prof. Bär wants to establish the infrastructure for in-situ and operando investigations of (photo)electrocatalytic materials.

The Bär Group is renowned for combining different lab- and synchrotron-based photon-in – electron-out and photon-in – photon-out spectroscopic methods to interrogate the chemical and electronic structure of energy conversion materials and thin-film layer stacks, with a particular focus on photovoltaics. The core expertise of the group is to non-destructively reveal composition and electronic structure profiles by deliberately employing different spectroscopies excited with soft and/or hard x-rays.

Most of the research activities evolve around the Energy Materials In-Situ Laboratory Berlin (EMIL), which is jointly operated by the Helmholtz-Zentrum Berlin für Materialien und Energie GmbH (HZB) and the Max-Planck Gesellschaft, and BESSY II, HZB’s synchrotron radiation facility. Prof. Bär heads the Department of “Interface Design”, which is responsible to run the HZB part of EMIL.
