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.
- Hatice Mutlu appointed to the Helmholtz Institute HIPOLE in JenaProf. Dr Hatice Mutlu is the new professor of sustainable polymer chemistry at HIPOLE Jena, the Helmholtz Institute for Polymers in Energy Applications. On 17 August 2026, she visited the HZB campus in Berlin-Adlershof including the BESSY II lightsource and discussed future collaboration with researchers and the board of directors.
- Green hydrogen with PEC electrolysers: New insights into transport processesOne method of storing solar energy is to use PEC electrolysers to produce hydrogen. However, scaling up this technology remains challenging. Now, a team at the HZB Institute for Solar Fuels has used 2D fluorescence imaging and particle velocimetry to observe the movement of ions and dissolved gases within the electrolyte during electrolysis. These new insights may prove useful in the development of larger PEC electrolysers.
- New contact material boosts the efficiency of perovskite solar cellsA newly developed material for the electron contact improves the efficiency of single perovskite solar cells and perovskite/silicon tandem solar cells. The new material is based on a carborane molecule. It offers several advantages over the standard material C60, as shown by the study led by Steve Albrecht’s team. The new material has since been patented and is already commercially available.
