Prof. Dr. Marcus Bär

Professorship of X-ray Spectroscopy, Helmholtz Institute Erlangen-Nürnberg for Renewable Energy (HI ERN)

Head of Department for ‘Interface Design’, Helmholtz-Zentrum Berlin für Materialien und Energie GmbH (HZB)

Head of Research Department ‘X-ray Spectroscopy at Interfaces of Thin Films’, Helmholtz Institute Erlangen-Nürnberg for Renewable Energy (HI ERN)

  • Combination of different lab and synchrotron-based photon-in electron-out and photon-in photon-out spectroscopic methods to investigate the chemical and electronic structure of energy conversion materials and thin-film layer stacks, with a particular focus on photovoltaics
  • Non-destructive analysis of the composition and electronic structure profiles by deliberately employing different spectroscopies excited with soft and/or hard x-rays
  • Establishment of the infrastructure for in-situ and operando investigations of (photo)electrocatalytic materials within the HI ERN activities is planned
  • Most of the research activities are carried out at the Energy Materials In-Situ Laboratory Berlin (EMIL), which is jointly operated by the HZB and the Max-Planck Society, and BESSY II, HZB’s synchrotron radiation facility
