15 young people start their careers at HZB
Welcome at HZB! © HZB/M. Setzpfandt
On 1 September, HZB welcomed 15 new employees who are starting an apprenticeship, a dual study programme or a voluntary year at HZB. At an introductory event at the Wannsee site, HZB's Administrative Director Thomas Frederking welcomed the new employees and wished them a good start at the research centre.
HZB has many years of experience and success in trainings and dual studies. The young people are supervised at the centre by highly motivated trainers. The HZB offers a very exciting environment with an international flair and many opportunities for personal development, Thomas Frederking emphasised during his welcoming speech.
We wish the new employees a good start and much success. Welcome to HZB! It's great to have you here.
The young people are in one of these training programmes:
- Precision mechanic
- Business Administrator for Office Management
- Cook
- IT Specialist (speciality System Integration)
- Computer Science (BSc)
- Design and Manufacture (B.Eng.)
- Voluntary Ecological Year
- Voluntary Social Year in Science, Technology and Sustainability

- A simpler way to inorganic perovskite solar cellsInorganic perovskite solar cells made of CsPbI3 are stable over the long term and achieve good efficiencies. A team led by Prof. Antonio Abate has now analysed surfaces and interfaces of CsPbI3 films, produced under different conditions, at BESSY II. The results show that annealing in ambient air does not have an adverse effect on the optoelectronic properties of the semiconductor film, but actually results in fewer defects. This could further simplify the mass production of inorganic perovskite solar cells.
- BESSY II: How pulsed charging enhances the service time of batteriesAn improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces ageing effects, an international team demonstrated. The study was led by Philipp Adelhelm (HZB and Humboldt University) in collaboration with teams from the Technical University of Berlin and Aalborg University in Denmark. Experiments at the X-ray source BESSY II were particularly revealing.
- Fuel Cells: Oxidation processes of phosphoric acid revealed by tender X-raysThe interactions between phosphoric acid and the platinum catalyst in high-temperature PEM fuel cells are more complex than previously assumed. Experiments at BESSY II with tender X-rays have decoded the multiple oxidation processes at the platinum-electrolyte interface. The results indicate that variations in humidity can influence some of these processes in order to increase the lifetime and efficiency of fuel cells.
