    Record- efficiency solar cells realised by the HyPerCells Graduate School

    The University of Potsdam and the Helmholtz-Zentrum Berlin founded the HyPerCells Graduate School just two years ago with focus on metal halide perovskites for solar applications. Now, groups involved in the graduate school have demonstrated perovskite solar cells with record-efficiencies of over 20 percent. This confirms the graduate school is at the forefront of this research in Germany and internationally highly competitive. [...].

    New magazine “lichtblick” is out: Select articles can be read in English on the website

    „The photon is our strength", said Bernd Rech. Since the 1st of May 2017, he has been the acting Scientific Director of HZB. In our new magazine "lichtblick" we spoke with him about his most important duties, the strengths of HZB, and surprises the job held in store. [...].

    User research at BER II: Lupin roots observed in the act of drinking

    Lupins not only produce colourful blossoms but also nutritious beans rich in proteins. Just how these plants draw water using their roots in the soil has now for the first time been observed in three dimensions by a University of Potsdam team at the HZB-BER II neutron source in Berlin. To accomplish this, they worked with the HZB imaging group to improve the temporal resolution of neutron tomography more than onehundred-fold so that a detailed 3D image was generated every ten seconds. This ultrafast neutron tomography is generally suitable as well for analyses of dynamic processes in porous materials. [...].

    Writing with the electron beam: now in silver

    For the first time an international team realized direct writing of  silver nanostructures using an electron beam applied to a substrate. Silver nanostructures have the potential to concentrate visible light at the nanoscale. Potential applications include sensor design to detect extremely small traces of specific molecules, as well as devices for optical information processing. [...].

    Modern, concise and informative: HZB presents itself

    A modern information brochure, illustrated throughout with a fusion of photos and sketches, serves as the new business card of HZB. In concise and understandable language, it describes the centre’s most important research focuses, introduces the large-scale facilities and laboratories, and shows why HZB is an internationally attractive place to work. [...].

    Nitrogen tank for the accelerator project bERLinPro was installed in Adlershof

    Rising 18 metres into the air, the nitrogen tank on the Helmholtz-Zentrum Berlin campus in Adlershof was installed on 18 July 2017. It can store up to 80 cubic metres of liquid nitrogen. This nitrogen will be used for pre-cooling the cooling system which is necessary for operating the new energy recovery linear accelerator (bERLinPro). The HZB experts are currently setting up a prototype for testing the potential of this accelerator technology. [...].

    Kickoff for Joint Lab with IFW Dresden

    The Leibniz Institute for Solid State and Materials Research Dresden (IFW) and Helmholtz-Zentrum Berlin (HZB) have created a Joint Lab for “functional quantum materials” and under its umbrella a Young Investigator Group.
