Welcome to the Helmholtz-Zentrum Berlin

At the Helmholtz Zentrum Berlin für Materialien und Energie (HZB), we conduct research on complex systems of materials that contributes to dealing with challenges such as the energy transition. The HZB research portfolio includes solar cells, solar fuels, thermoelectrics, and materials for new, energy-efficient information technologies (spintronics) or electrochemical energy storage. Research on these energy materials is closely connected with the operation and advanced development of the BESSY II photon source. And our research approach always concentrates on thin-film technologies. Find out more at this About us.

    Accelerator physics: alternative material investigated for superconducting radio-frequency cavity resonators

    In modern synchrotron sources and free-electron lasers, superconducting radio-frequency cavity resonators are able to supply electron bunches with extremely high energy. These resonators are currently constructed of pure niobium. Now an international collaboration has investigated the potential advantages a niobium-tin coating might offer in comparison to pure niobium. [...]

    Oldest completely preserved lily discovered

    Already 115 million years ago, tropical flowering plants were apparently very diverse and showed all typical characteristics. This is the conclusion of an international team of researchers led by Clément Coiffard, Museum für Naturkunde Berlin. The team reported in the renowned journal Nature Plants on the oldest completely preserved lily, Cratolirion bognerianum, which was discovered at a site in present-day Brazil. With the help of 3D computer tomography at the Helmholtz-Zentrum Berlin, details on the back of the fossilised plant could also be analysed. The results raise new questions about the role of the tropics in the development of past and present ecosystems. [...]

    Charge transfer within transition-metal dyes analysed

    Transition-metal complexes in dye-based solar cells are responsible for converting light into electrical energy. A model of spatial charge separation within the molecule has been used to describe this conversion. However, an analysis at BESSY II shows that this description of the process is too simple. For the first time, a team there has investigated the fundamental photochemical processes around the metal atom and its ligands. The study has now been published in “Angewandte Chemie, international Edition” and is displayed on the cover. [...]
