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.
- BESSY II: Evaporated perovskites in tandem solar cells improvedPerovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the silicon subcell. Scientists at HZB have analysed film growth on the nanoscale at BESSY II and found a new way to improve the quality of the perovskite layer: adding a thin seed layer of caesium chloride between the two sub-cells promotes uniform perovskite growth and suppresses the formation of undesired lead iodide at the interface.
- Hatice Mutlu appointed to the Helmholtz Institute HIPOLE in JenaProf. Dr Hatice Mutlu is the new professor of sustainable polymer chemistry at HIPOLE Jena, the Helmholtz Institute for Polymers in Energy Applications. On 17 August 2026, she visited the HZB campus in Berlin-Adlershof including the BESSY II lightsource and discussed future collaboration with researchers and the board of directors.
- Green hydrogen with PEC electrolysers: New insights into transport processesOne method of storing solar energy is to use PEC electrolysers to produce hydrogen. However, scaling up this technology remains challenging. Now, a team at the HZB Institute for Solar Fuels has used 2D fluorescence imaging and particle velocimetry to observe the movement of ions and dissolved gases within the electrolyte during electrolysis. These new insights may prove useful in the development of larger PEC electrolysers.
