Working fields: Organic and Hybrid Photovoltaics, Heterogeneous Catalysis

Dr. Holger Borchert studied physics in Hamburg and Paris. He worked then as a Ph.D. student in the group of Prof. Dr. Horst Weller at the institute of Physical Chemistry of the University of Hamburg where he studied surface properties of colloidally prepared nanocrystals by photoelectron spectroscopy. After the Ph.D. study, he went for one year to Russia and worked as a DAAD fellow at the Boreskov Institute of Catalysis in Novosibirsk. There he studied nanostructured, doped cerium dioxide in the groups of Prof. Vladislav A. Sadykov and Prof. Valerii I. Bukhtiyarov. After his return to Germany, Dr. Borchert worked as research assistant in the groups of Prof. Dr. Katharina Al-Shamery at the Institute of Pure and Applied Chemistry of the University of Oldenburg and Prof. Dr. Marcus Bäumer at the Institute of Applied and Physical Chemistry of the University of Bremen. Research focussed now on model catalytic studies of highly ordered surfaces under ultrahigh vacuum conditions and well-defined particle systems under ambient pressure conditions. In 2007, Holger Borchert moved to the group of Prof. Dr. Jürgen Parisi at the Department of Physics of the University of Oldenburg, where he became in charge of the subdivision for hybrid photovoltaics and in parallel continued activities in the field of heterogeneous catalysis - two application fields of colloidally prepared nanoparticles in the superior research area of environmental science / energy technology. These fields were also the topic for the habilitation which was successfully completed in 2011. Since then, the range of research activities was further enlarged to purely organic polymer/fullerene solar cells.
