HZB is member of the IGAFA initiative in Adlershof
What are the activities of IGAFA?
Since September 2020, the Helmholtz-Zentrum Berlin is again a member of IGAFA - the Initiative of Non-University Research Institutions in Adlershof. Prof. Dr. Jan Lüning, scientific director of the HZB, was elected to the association's board.
The tasks of IGAFA include the promotion of interdisciplinary cooperation, the promoting of scientific content through publications and events and the care of international guests in two meeting centers (see figure).
In addition, IGAFA sees itself as an interface between research and the public interested in science. For this reason, IGAFA participates, for example, in the Adlershof Dissertation Prize, the Long Night of Sciences, or supervises the Adlershof Ladies Network.
- 3D magnetic field experiment at BESSY II takes spintronics a step further(Fe0.63Ni0.3Pd0.07)3P or FNPP is a magnetic material that exhibits complex magnetic structures even at room temperature. This makes the material of interest for spintronics, a field that could enable data processing with significantly lower energy consumption. One potential application is novel magnetic memory devices. However, generating and modifying the desired structures in a controlled manner remains a challenge to date. A new study led by HZB has now taken a step forward in this regard. They demonstrated at the worldwide unique VEKMAG-Station at BESSY II, that a tiny external B-field in the plane of the magnetic patterns is sufficient to change them.
- BESSY II: Evaporated perovskites in tandem solar cells improvedPerovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the silicon subcell. Scientists at HZB have analysed film growth on the nanoscale at BESSY II and found a new way to improve the quality of the perovskite layer: adding a thin seed layer of caesium chloride between the two sub-cells promotes uniform perovskite growth and suppresses the formation of undesired lead iodide at the interface.
