In 2024, two young scientists joined HZB as Humboldt Fellows. Kazuki Morita joined Prof. Antonio Abate's group and brings his expertise in modelling and data analysis to solar energy research. Qingping Wu is an expert in battery research and works with Prof. Yan Lu on high energy density lithium metal batteries.
“I chose to come to HZB because of its outstanding reputation in materials and energy research and the opportunity to work with Prof. Yan Lu and her team on cutting-edge electrochemical storage technologies,” says Qingping Wu. A chemist by training, Wu completed his PhD in chemical engineering in 2021 and worked as an assistant professor at the Chongqing Institute of Green and Intelligent Technology in China. He joined HZB in August 2024 and will stay until the end of July 2026. His research focuses on aging mechanisms and optimisation of electrode/electrolyte interfaces for high energy density lithium metal batteries.
Kazuki Morita earned his PhD from the Department of Materials, Imperial College London, UK, in 2022. He was a postdoctoral scientist at the Department of Chemistry, University of Pennsylvania, USA before joining the team of Prof. Antonio Abate with a Humboldt-Fellowship in May 2024 for the next two years. “I have been reading papers from HZB including ones from Antonio's since I was a PhD student. HZB is an ideal environment to pursue my research,” he says. He will study the stability of tin halide perovskites. “In particular, I will investigate the tin oxidation process using theory and simulations, which is my area of expertise. Prof. Antonio Abate primarily focuses mainly on experiments, so our expertise is complementary,” he says.
- New Helmholtz Young Investigator Group at HZB on perovskite solar cellsSilvia Mariotti is returning to HZB as head of the new Helmholtz Young Investigator Group ‘Perovskite-based multi-junction solar cells’. The perovskite expert, who was previously based at Okinawa University in Japan, aims to advance the development of multi-junction solar cells made from different perovskite layers.
- Hydrogen storage in MXene: It all depends on diffusion processesTwo-dimensional (2D) materials such as MXene are of great interest for hydrogen storage. An expert from HZB has investigated the diffusion of hydrogen in MXene using density functional theory. This modelling provides valuable insights into the key diffusion mechanisms and hydrogen's interaction with Ti₃C₂ MXene, offering a solid foundation for further experimental research.
- Excellent work-life balance continuesOn 17 June 2025, the certificates for the ‘berufundfamilie’ audit were awarded in Berlin. HZB received an award with distinction for its long-standing efforts to promote a work environment that supports work-life balance. The audit is regarded as a seal of quality for the systematic design of family- and life-phase-conscious HR policies.
