On 23 April 2026, the annual Girl’s Day took place, giving pupils an insight into various career paths in the fields of science and technology. 83 pupils visited the Adlershof and Wannsee sites and enjoyed a day full of exciting experiments.
By taking part in various workshops, the girls were able to gain an insight into careers such as physicist, engineer and chemist.
Girls’ Day is an important initiative designed to inspire pupils to take an interest in science and technology and to encourage them to pursue careers in these fields.
HZB’s research topics were explored in a fun and engaging way across 16 different workshops.
Wannsee:
- Jules Verne’s dream: water as the coal of the future
- Using colours, electricity and chemistry, we make the invisible visible!
- Kitchen Tetris in the canteen’s shell
- Basics of HTML & CSS
- Atom by atom – thin films for the technology of the future
- Crystals – how are they structured and how can they be studied?
- Creative programming
Smart wires in the student lab
Adlershof:
- Particle accelerators – big and small
- Hot Stuff – solar energy you can touch (almost!)
- Soldering LED earrings
- The daily work of laboratory technicians at HZB and the production of perovskite solar cells
- The power of metadata: tagging, searching, finding!
- Chocolate lithography and what it has to do with solar cells
- Light programming: a creative introduction to programming
- Molecule detectives: searching for clues with NMR
We would like to extend our heartfelt thanks to all our colleagues whose dedication helped ensure that Girls’ Day at HZB could take place with such a diverse and exciting range of workshops.
The next opportunity to get to know us and carry out small experiments yourself will be at the Long Night of Science on 6 June at the HZB Adlershof site. With lots of exciting activities especially for children and young people!
- Zum Girls' Day: Was eine Professorin rätChristiane Becker ist Physikerin am Helmholtz-Zentrum Berlin und Professorin. Sie forscht daran, wie Solarzellen noch besser werden können. Im Gespräch mit Schülerpraktikantin Livia gibt sie einen Einblick in ihren Arbeitsalltag und ihre Erfahrungen in der Forschung und hat einen Tipp für alle Mädchen, die sich für Wissenschaft begeistern.
- Electrocatalysts: New model for charge separation at the solid-liquid interfaceHydrogen is at the heart of the transition to carbon neutrality, as both an energy carrier and a reagent for green chemistry. However, large-scale production of hydrogen via electrolysis, as well as the production of many other chemical products, requires significantly cheaper and more efficient catalysts. A precise understanding of the electrochemical processes that take place at the interface between the solid catalyst and the liquid medium is highly useful for developing better electrocatalysts. In the journal Nature Communications, an European team has now presented a powerful model that determines charge separation at the interface, the formation of the electric double layer and local electric potential variations, and the resulting influence on the catalytic activity.
