On 6 June 2026, we opened our doors once again for the Long Night of Science. With 3,100 visitors, BESSY II welcomed 500 more people than last time. We would like to thank everyone for their interest! We captured the best moments of the evening in the photo gallery.
The tour of the BESSY II accelerator was packed in many places. Lots of people stood on the bridge, marvelling at the experiments and asking plenty of questions. The hands-on experiments were once again particularly popular. There was also a crowd at the stands run by the Competence Centre for Photovoltaics, Battery Research and Protein Crystallography. The BESSY III team provided information about the new successor facility and received a great deal of positive feedback from our guests.
On Instagram there is a video with highlights from the evening.
“This is not something to be taken for granted” – Great interest in science across Berlin
“The Long Night of Science in Berlin is the largest science festival in the whole of Germany. Almost 60 institutions and many researchers are involved. We had around 30,000 visitors – that’s not something to be taken for granted. What better way to build support for science than through direct encounters?” says Dr Christina Quensel, Managing Director of the Long Night of Science Association.
The next Long Night of Science is scheduled for 19 June 2027.
- Perovskite triple-junction solar cells: Even more efficient with GO/SAM bilayersPerovskite semiconductors efficiently convert sunlight into electrical energy; they are also inexpensive and extremely lightweight. A team at HZB has developed a triple-junction solar cell comprising different perovskite semiconductors, with a novel bilayer of graphene oxide (GO) and a self-assembled monolayer (SAM) as the hole conductor. This bilayer significantly increases both efficiency and long-term stability. The efficiency of the novel perovskite triple-junction solar cell is 27.3% and shows hardly any decline even after more than 770 hours of operation. The study has been published in the renowned journal Joule.
- Green Deal Ukraїna at the Ukraine Recovery ConferenceEnd of June, the Ukraine Recovery Conference (UCR2026) took place in Gdańsk, Poland. Unlike previous editions, URC2026 introduced a dedicated Energy Platform, jointly organised by the Ministry of Energy of Ukraine and the Ministry of Climate and Environment of Poland, which brought together energy-related discussions, announcements, and side events in one place, increasing the visibility and coordination of key energy topics. Green Deal Ukraїna, an initiative coordinated by HZB, organised three events on the sidelines of URC on research and energy topics as part of the conference.
- VOLT – Art in the shell of the HZB from 19 to 21 June 2026An extraordinary setting: from 19 to 21 June, artists and students from the Berlin University of the Arts will be exhibiting in the shell of the services building on the HZB campus in Berlin-Adlershof. The public is warmly invited to attend the three-day exhibition.
