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.
- Long-term stability for perovskite solar cells: a big step forwardPerovskite solar cells are inexpensive to produce and generate a high amount of electric power per surface area. However, they are not yet stable enough, losing efficiency more rapidly than the silicon market standard. Now, an international team led by Prof. Dr. Antonio Abate has dramatically increased their stability by applying a novel coating to the interface between the surface of the perovskite and the top contact layer. This has even boosted efficiency to almost 27%, which represents the state-of-the-art. After 1,200 hours of continuous operation under standard illumination, no decrease in efficiency was observed. The study involved research teams from China, Italy, Switzerland and Germany and has been published in Nature Photonics.
- Two precision mechanics from HZB are Berlin's best traineesTwo former apprentices from the HZB workshop have achieved something remarkable: Fiete Buchin and Edgar Lunk completed their training as precision mechanics, taking first and second place in all of Berlin. In this interview, they share what it took to reach the top, what makes their training special, and the advice they would give to future apprentices.
- Successful master's degree in IR thermography on solar facadesWe are delighted to congratulate our student employee Luca Raschke on successfully completing her Master's degree in Renewable Energies at the Hochschule für Technik und Wirtschaft Berlin - and with distinction!
