Bernd Stannowski is Professor at the Beuth University of Applied Sciences Berlin
Prof. Dr. Bernd Stannowski has received and accepted a call for a joint S-Professorship for "Photovoltaics" at the Beuth University of Applied Sciences Berlin. The physicist heads the working group "Silicon Photovoltaics" at the Competence Center Thin Film and Nanotechnology for Photovoltaics Berlin (PVcomB) of the HZB.
Bernd Stannowski has been teaching since the winter semester 2018/19 in the course of studies "Physical Technology" in Faculty 2 "Mathematical Physics and Chemistry" at the Beuth University. Currently he teaches "Semiconductor Physics" and "Thermodynamics"; a lecture on "PV/Regenerative Energy" is planned. The call was made on 18 March 2019.
With his research group at PVcomB Bernd Stannowski develops and optimizes materials and manufacturing processes for silicon solar cells and thin film technologies - with a focus on industrial applications. The focal points of his working group include silicon heterojunction solar cells, which are used as efficient bottom cells for silicon perovskite tandem solar cells.
Bernd Stannowski has been working at the PVcomB of the Helmholtz-Zentrum Berlin since October 2010. Before moving to research, he worked for 8 years in the PV industry and, among others, headed the process development at a thin-film photovoltaic manufacturer. He studied physics at the University of Duisburg-Essen and the RWTH Aachen. Then he completed his doctorate at the University of Utrecht, Netherlands, where he also worked as a postdoc researcher.
- The twisted nanotubes that tell a storyIn collaboration with scientists in Germany, EPFL researchers have demonstrated that the spiral geometry of tiny, twisted magnetic tubes can be leveraged to transmit data based on quasiparticles called magnons, rather than electrons.
- Bright prospects for tin perovskite solar cellsPerovskite solar cells are widely regarded as the next generation photovoltaic technology. However, they are not yet stable enough in the long term for widespread commercial use. One reason for this is migrating ions, which cause degradation of the semiconducting material over time. A team from HZB and the University of Potsdam has now investigated the ion density in four different, widely used perovskite compounds and discovered significant differences. Tin perovskite semiconductors produced with an alternative solvent had a particular low ion density — only one tenth that of lead perovskite semiconductors. This suggests that tin-based perovskites could be used to make solar cells that are not only really environmentally friendly but also very stable.
