On 25 and 26 November 2015, about 40 researchers from seven European countries visited Helmholtz-Zentrum Berlin to attend the “European Workshop on Nanophotonics for Solar Energy”.
During this workshop, current trends and developments in this field were discussed. Further, future opportunities and possibilities for collaboration were explored during discussions, which were initiated with a talk on funding within the European Commission Horizon 2020 program by Dr. David Kolman from the Brussels Office of the Helmholtz Association. The highlight of the workshop was the Distinguished Lecture by Prof. Thomas F. Krauss from the University of York (UK), in which he shared his vision on the future of Photovoltaics and informed us about the latest research results from his group.
This workshop was initiated and organized by Christiane Becker, Sven Burger and Klaus Jäger within the Berlin Joint Lab for Optical Simulations for Energy (BerOSE), which is a collaboration between Helmholtz-Zentrum Berlin, Zuse Institute Berlin and the Free University Berlin.
- Marcel Risch has been appointed Professor at the Freie Universität BerlinMarcel Risch was appointed to a W2-S professorship in the Department of Physics at Freie Universität Berlin in August 2026. His research group has been transformed into the department 'Mechanisms of Sustainable Electrocatalysis'. Risch investigates the fundamental mechanisms of electrocatalytic reactions and, on this basis, develops knowledge- and data-driven strategies to improve electrocatalysts for the sustainable production of hydrogen, fuels and chemicals.
- 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.
