HZB to participate in two Clusters of Excellence
Scientists at the Helmholtz-Zentrum Berlin (HZB) are researching novel systems of materials that can convert or store energy. The HZB will now also be contributing this expertise to the "MATH+" and "UniSysCat" Excellence Clusters being coordinated by Berlin universities. Over the next three years, the Helmholtz Association will fund HZB's participation under the Helmholtz Excellence Network with a total of 1.8 million euros.
Prof. Christiane Becker, who heads the Nanooptics Group at HZB in the Renewable Energies division, is involved in the "MATH+" Excellence Cluster. Becker investigates and develops optoelectronic materials with nanoscale features for solar cells and sensors and cooperates closely with mathematicians in MATH+. Their common goal is the development of highly efficient next-generation solar energy technologies, such as improved light management in tandem perovskite-silicon solar cells, for example. They will also work together on hybrid components for the production of solar fuels and develop simulation and optimisation methods.
MATH+ partner
MATH+ is the short name for "Forschungszentrum der Berliner Mathematik / Berlin Mathematics Research Center". The Freie Universität Berlin, Humboldt-Universität zu Berlin and Technische Universität Berlin as well as the Weierstrass Institute for Applied Analysis and Stochastics and the Zuse Institute Berlin are all participating in this project. The Helmholtz Association will fund HZB's participation with 800,000 euros from the Helmholtz Initiative and Networking Fund over the next three years.
UniSysCat: Focus on catalysis
Researchers in the "UniSysCat" (Unifying Systems in Catalysis) Excellence Cluster are developing complex catalytic systems. They focus on catalytic processes that are activated by sunlight. “These processes make it possible to use sunlight for generation of chemical fuels as well as for high energy-density compounds in a sustainable way. A particular challenge here is to link the rapid absorption processes in semiconductor materials with the often much slower electrochemical reactions of the bound catalyst“, explains Prof. Roel van de Krol, head of the HZB Institute for Solar Fuels. The HZB is contributing its particular expertise in material synthesis of thin-film absorbers, photoelectrochemistry, and time-resolved optical spectroscopy.
UniSysCat partner
UniSysCat is being coordinated by the Technische Universität Berlin. In addition, teams from Freie Universität Berlin, Humboldt-Universität zu Berlin, the University of Potsdam, Charité Universitätsmedizin Berlin, Fritz Haber Institute, Max Planck Institute of Colloids and Interfaces (MPIKG), and the Leibniz Institute for Molecular Pharmacology (FMP) are also participating. The Helmholtz Association will fund the HZB‘s participation with 1 million euros over the next three years from the Helmholtz Initiative and Networking Fund.
- New Helmholtz Young Investigator Group at HZB on perovskite solar cellsSilvia Mariotti starts building up 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.
- HZB and National University Kyiv-Mohyla Academy start cooperation in Energy and ClimateHelmholtz-Zentrum Berlin für Materialien und Energie GmbH (HZB) and the National University of "Kyiv-Mohyla Academy" (NaUKMA) have signed a Memorandum of Understanding (MoU). The MoU serves as the starting point for collaborative research, academic exchange, and capacity-building between the two institutions. Actions will be taken to establish the Joint Research and Policy Laboratory at NaUKMA in Kyiv. The aim of the future laboratory is to jointly develop research and policy analysis, focusing on the energy and climate dimensions of Ukraine’s EU integration.
