HZB participates in a new consortium for Perovskite solar technology that is led by Oxford PV Germany GmbH. The consortium is funded by the German Ministry of Economics and Energy with 2.8 Million Euros and aims to further demonstrate the manufacturability of perovskite-silicon tandem solar cells.
Further partners are Von Ardenne GmbH, Fraunhofer-Institute for Solar Energy Systems ISE, and the Technical University of Berlin. The project will focus on preparing perovskite solar cell technology for high volume manufacturing. This will include the optimisation of the perovskite-silicon tandem solar cell architecture, to make further efficiency improvements on industrial 156 mm x 156 mm wafer formats; the refinement of industrial scale process technology; and life-cycle analysis to inform the social-environmental impact of the tandem solar cells.
"Perovskite-based tandem solar cells are very promising to achieve really high efficiencies. In order to contribute to this exciting development we have built up strong competences in perovskites and tandem cell technology such as the Helmholtz Innovation Lab HySPRINT", says Prof. Dr. Rutger Schlatmann, Director of the Competence Center Thin Film and Nanotechnology for Photovoltaics Berlin (PVcomB) at HZB. "To the consortium with Oxford PV, we contribute our vast expertise in high-efficiency silicon heterojunction bottom cells", adds Dr. Bernd Stannowski who is leading these activities at the PVcomB.
Dr. Chris Case, Chief Technology Officer at Oxford PV says “The consortium partners bring together the perfect balance of expertise. Refining the manufacturing process of our perovskite solar cell technology will ensure the highest performing tandem solar cell in the field and the easy transfer of our technology into silicon solar cell and module production lines.”
In June 2018, HZB and Oxford achieved an independently certified efficiency of 25.2 % for their perovskite silicon tandem solar cell. “In our cooperation, we aim to further optimize perovskite silicon tandem cells, demonstrate their scalability and facilitate their integration into large-area solar modules”, says Rutger Schlatmann.

- A New Era in Catalysis: ASCEND Launch in Berlin, €30 Million in FundingOn 11 June 2026, the Helmholtz-Zentrum Berlin (HZB) in Adlershof hosted the launch of ASCEND (Accelerated Solutions for Catalysis using Emerging Nanotechnology and Digital Innovation). The event took place in the presence of the Minister of Research, Dorothee Bär, President of the Helmholtz Association, Prof. Dr. Martin Keller, and President of the Max Planck Society, Prof. Dr. Patrick Cramer. Bringing together leading partners from industry and research, ASCEND is supported by BMFTR with €30 million in funding and officially started on 1 April 2026. The initiative aims to accelerate the discovery of next-generation catalysts and enable more sustainable chemical processes.
- Magnon momentum microscopy: A new window into nanoscale spin-wavesAn international team lead by the Max Born Institute has developed a new type of momentum microscopy to image magnons — the quanta of collectively excited spins — directly in two-dimensional reciprocal space using soft X-rays. Measurements have taken place at BESSY II and PETRA III, first author ist the HZB physicist Steffen Wittrock. Owing to its remarkable sensitivity, simplicity, and access to nanometer-scale wavelengths, this novel technique establishes a powerful and versatile platform for exploring nonlinear magnon interactions, which are promising for future computing schemes.
- X-ray analysis reveals overpainted fascist symbolsErich Mercker was a successful painter during the Nazi era and in the years that followed. After 1945, he covered up Nazi symbols in at least one of his paintings. With an interdisciplinary team, physicist Dr Ioanna Mantouvalou reports on this study in the Nature Journal Heritage Science.
