Prof. Marcus Bär has accepted a professorship for X-ray spectroscopy at the Friedrich-Alexander Universität Erlangen-Nürnberg (FAU). Bär heads the Department of Interface Design at Helmholtz-Zentrum Berlin (HZB). The new W2 professorship was established in cooperation with HZB and Forschungszentrum Jülich in order to strengthen the Helmholtz-Institute Erlangen-Nürnberg für Renewable Energy (HI ERN). In the future, Bär will also be working on HI ERN research topics at HZB, thereby contributing to the intensification of cooperation.

Marcus Bär studied physics at the University of Potsdam and Environmental Engineering/Renewable Energies at the University of Applied Sciences (FHTW) in Berlin. In 2003 he earned his doctorate in electrical engineering in the field of solar energy research at the Hahn-Meitner-Institut Berlin and at the TU Berlin. Thereafter, Prof. Bär was Emmy-Noether Fellow at the Department of Chemistry of the University of Nevada in Las Vegas/USA. He was promoted to an Adjunct Assistant Research Professor at this department in 2006 and to an Assistant Research Professor in 2007. In 2009 he returned to Berlin and became head of the Helmholtz Young Investigator Group "Improving thin-film solar cells by deliberate interface tailoring" at the HZB. Two years later he was appointed professor for photovoltaics at the BTU Cottbus-Senftenberg.

Prof. Bär's research interests lie in the field of X-ray spectroscopic investigation of the chemical and electronic structure of energy-conversion materials and structures with a focus on thin-film solar cells. In the future, Prof. Bär wants to establish the infrastructure for in-situ and operando investigations of (photo/electro)catalytic materials, which are also interesting to the HI ERN researchers.

    Perovskite triple-junction solar cells: Even more efficient with GO/SAM bilayers
    Perovskite semiconductors efficiently convert sunlight into electrical energy; they are also inexpensive and extremely lightweight. A team at HZB has developed a triple-junction solar cell comprising different perovskite semiconductors, with a novel bilayer of graphene oxide (GO) and a self-assembled monolayer (SAM) as the hole conductor. This bilayer significantly increases both efficiency and long-term stability. The efficiency of the novel perovskite triple-junction solar cell is 27.3% and shows hardly any decline even after more than 770 hours of operation. The study has been published in the renowned journal Joule.

    End of June, the Ukraine Recovery Conference (UCR2026) took place in Gdańsk, Poland. Unlike previous editions, URC2026 introduced a dedicated Energy Platform, jointly organised by the Ministry of Energy of Ukraine and the Ministry of Climate and Environment of Poland, which brought together energy-related discussions, announcements, and side events in one place, increasing the visibility and coordination of key energy topics. Green Deal Ukraїna, an initiative coordinated by HZB, organised three events on the sidelines of URC on research and energy topics as part of the conference.
