Perovskite solar technology leader Oxford PV collaborates with leading German research centre to support the accelerated transfer of its technology into silicon cell manufacturing lines.
Oxford PVTM – The Perovskite CompanyTM, the leader in the field of perovskite solar cells, today announced its collaboration with Helmholtz-Zentrum Berlin (HZB), the leading German research centre focused on energy materials research.
Oxford PV has made considerable progress in transferring its advanced perovskite on silicon tandem solar cell technology from its laboratory in Oxford, UK to an industrial scale process at its site in Brandenburg an der Havel, Germany.
HZB’s extensive expertise in silicon heterojunctions solar cell technology, will support Oxford PV to further optimise its perovskite on silicon tandem solar cell technology, and demonstrate production scale up, to ensure ease of integration into large scale silicon solar cell and module production.
“Working with HZB to understand solar cell manufacturers’ silicon cells, will allow Oxford PV’s perovskite on silicon tandem formation to be fully optimised, to ensure the most efficient tandem solar cell, and the easy transfer of our technology into our commercial partner’s industrial processes, commented Chris Case, Chief Technology Officer, at Oxford PV,
“Oxford PV is now in the final stage of commercialising its perovskite photovoltaic solution, which has the potential to enable efficiency gains that will transform the economics of silicon photovoltaic technology globally.”
Rutger Schlatmann, Director of the PVcomB institute at HZB, said, “HZB believe that perovskites present a significant opportunity to the future of photovoltaics. For this reason, at our new innovation lab - HySPRINT, we have significantly increased our expertise and attracted some of the most promising young scientists in this field. HZB’s collaboration with Oxford PV is strategically important to the institute, as Oxford PV is the ideal partner to further develop our solar cell technology knowledge and help support the commercialisation of tandem silicon perovskite photovoltaic cells.”

- Thin nickel films boost green hydrogen productionUltra-thin nickel oxide coatings can significantly improve the performance of anion exchange membrane (AEM) water electrolysers, a promising technology for producing green hydrogen. This was demonstrated by a team led by HZB scientist Dr. Michelle Browne. The results show that a nickel oxide film only 10 nanometres thick outperformed conventional nickel oxide powder electrodes while using less than 1% of the catalyst material. The study is published in the Journal of Materials Chemistry A,
- 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.
