New HZB magazine "Lichtblick" has been published
In the new issue, we introduce our new commercial managing director. We also show how important exchange is to us: science thrives on fruitful exchange with others. But dialogue with the public is also very important to us. Art can also create enriching access to science and build bridges. All these topics are covered in the new issue of Lichtblick.

A portrait of our Administrative director
The new Administrative Director, Saskia Vormfelde, took up her work in September – and brings more than just a knack for balance sheets to the table. You can read about what she has done so far and why she is looking forward to working at HZB in the cover story. > Portrait on the internet
What remains of the Helmholtz reviews in May?
Many colleagues were busy preparing for the programme-oriented research (PoF) reviews in the first half of 2025. In an interview, the two coordinators, Olaf Schwarzkopf and Tobias Sontheimer, talk about how the presentation was received by the reviewers. > Interview to read
The neuron accelerator brings art and research together
A place that invites brainstorming: artist Peter Sandhaus' neuron accelerator is designed to strengthen exchange and stimulate new ideas. The artwork has recently been installed in front of the entrance to the BESSY II building. > More about the artwork

Good advice in the service of science: Sebastian Fiechter is a long-standing ombudsperson for good scientific practice and talks about the problems that can arise.
Why we are becoming more public: Dialogue and exchange on an equal footing help to build trust in science. That's why we approach people at many festivals.
The internationality of our employees: How international are we really?
- The twisted nanotubes that tell a storyIn collaboration with scientists in Germany, EPFL researchers have demonstrated that the spiral geometry of tiny, twisted magnetic tubes can be leveraged to transmit data based on quasiparticles called magnons, rather than electrons.
- Bright prospects for tin perovskite solar cellsPerovskite solar cells are widely regarded as the next generation photovoltaic technology. However, they are not yet stable enough in the long term for widespread commercial use. One reason for this is migrating ions, which cause degradation of the semiconducting material over time. A team from HZB and the University of Potsdam has now investigated the ion density in four different, widely used perovskite compounds and discovered significant differences. Tin perovskite semiconductors produced with an alternative solvent had a particular low ion density — only one tenth that of lead perovskite semiconductors. This suggests that tin-based perovskites could be used to make solar cells that are not only really environmentally friendly but also very stable.
