Helmholtz-Zentrum Berlin für Materialien und Energie
The Helmholtz-Zentrum Berlin (HZB) became the target of a cyber attack on June 15, 2023. To protect itself, the center has shut down all IT systems. These will gradually be put back into operation. Nevertheless, we are still only accessible to a limited extent. After our website was offline for a longer time, you will find important info there again.

We are working on highly efficient solar cells of the next generations, for example on thin-film technologies and new classes of materials such as perovskites. In doing so, we seek contact with industry at an early stage. We are developing novel catalysts and materials that convert sunlight into chemical energy and thus produce renewable fuels, for example hydrogen. Battery materials with better properties are also being explored at HZB. Another important field of research is quantum materials for tomorrow's energy-efficient information technologies.
Lightsource BESSY II
One of HZB's main focuses is the operation of the synchrotron radiation source BESSY II, which is not only an important tool for researchers at HZB, but is also available to the international scientific community. BESSY II generates highly brilliant synchrotron light, which is guided to the experiments via 40 beamlines. The facility is optimized for soft X-ray light, which is particularly suitable for analyzing chemical processes at surfaces and within thin layers.
3,000 guest scientists from all disciplines
The BESSY II storage ring receives more than 3,000 visits per year from guest researchers from research and industry. They come from a wide range of disciplines, from chemistry, physics, biology, geology to cultural history. For example, they decipher the architecture of proteins, look inside viruses and bacteria, map magnetic patterns in meteorites or analyze band structures of semiconductor materials. Their results help to develop, for example, drugs and processes to split up and recycle the plastic PET. The synchrotron light from BESSY II is indispensable for such experiments, and unique in Germany.
User research is as diverse as the instruments and methods at BESSY II, which are constantly being improved by HZB teams. In order to meet the needs of guest researchers and industry in the long term, HZB's experts are already working on concepts for a successor light source.
The Helmholtz-Zentrum Berlin (HZB) was founded in 2009 by merging the former Hahn-Meitner-Institut (founded 1959) and the BESSY-Gesellschaft (founded 1979). With approximately 1200 employees, HZB is one of the largest non-university research centers in Berlin.
