At the 5th International Conference on Perovskite Solar Cells and Optoelectronics (PSCO-19) Dr. Götz Schuck received a prize for his poster contribution. The international conference took place from 30.09.2019 to 02.10.2019 in Lausanne, Switzerland.
Halide Perovskites are outstanding candidates for extremely efficient and yet cost-effective solar cells. In the most studied perovskite variant, the lattice sites of a perovskite structure are occupied by the halide element iodine, the metal lead and the organic molecule methylammonium. But what happens when iodine is replaced by chlorine?
Götz Schuck investigated this question using neutron scattering experiments and other methods. He presented the results on his poster titled "Influence of chloride substitution on the rotational dynamics of methylammonium in MAPb(I,Cl)3 perovskites".
"This award shows the high quality of Götz Schuck's research on the dynamic structure of halide perovskites", says Prof. Dr. Susan Schorr, head of the department Structure and Dynamics of Energy Materials. At the conference 150 posters have been presented, 7 of which were awarded with a poster prize.
- Two Humboldt-Fellows join HZBIn 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.
- Ultrafast dissociation of molecules studied at BESSY IIFor the first time, an international team has tracked at BESSY II how heavy molecules – in this case bromochloromethane – disintegrate into smaller fragments when they absorb X-ray light. Using a newly developed analytical method, they were able to visualise the ultrafast dynamics of this process. In this process, the X-ray photons trigger a "molecular catapult effect": light atomic groups are ejected first, similar to projectiles fired from a catapult, while the heavier atoms - bromine and chlorine - separate more slowly.
- Battery research with the HZB X-ray microscopeNew cathode materials are being developed to further increase the capacity of lithium batteries. Multilayer lithium-rich transition metal oxides (LRTMOs) offer particularly high energy density. However, their capacity decreases with each charging cycle due to structural and chemical changes. Using X-ray methods at BESSY II, teams from several Chinese research institutions have now investigated these changes for the first time with highest precision: at the unique X-ray microscope, they were able to observe morphological and structural developments on the nanometre scale and also clarify chemical changes.
