    10 Years of Helmholtz-Zentrum Berlin: A strong partner in the scientific landscape

    Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) is celebrating its tenth anniversary on 18 February 2019 with around 250 invited guests from science, politics and industry. The Centre is one of the world's top institutions and makes a decisive contribution to Berlin as a location for cutting-edge research. This was emphasized by Michael Müller, Governing Mayor of Berlin, in reference to the anniversary. [...]

    Spintronics by “straintronics”: Superferromagnetism with electric-field induced strain
    Data storage in today’s magnetic media is very energy consuming. Combination of novel materials and the coupling between their properties could reduce the energy needed to control magnetic memories thus contributing to a smaller carbon footprint of the IT sector. Now an international team led by HZB has observed at the HZB lightsource BESSY II a new phenomenon in iron nanograins: whereas normally the magnetic moments of the iron grains are disordered with respect each other at room temperature, this can be changed by applying an electric field: This field induces locally a strain on the system leading to the formation of a so-called superferromagnetic ordered state.

    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. [...]

    Towards the Climate Neutral City: Independent consulting office for integrating photovoltaics into buildings
    The Helmholtz-Zentrum Berlin is opening a national consulting office for integrating photovoltaics into buildings (BAIP) this spring. The consulting office will support building owners, architects, and municipal planners in activating building envelopes for power generation. The project is being funded by the Helmholtz Association over a period of four years as part of its knowledge transfer programme.

    Ultra-thin and extremely efficient: Thin-film tandem cells made of perovskite and CIGSe semiconductors
    An HZB team has fabricated and characterised a thin-film tandem solar cell made of perovskite and CIGSe. They relied on a simple, robust fabrication process that is also suitable for scaling up to large surface areas. The tandem solar cell is a fully thin film device with an impressive efficiency of 21.6 %. With further improvements it might reach efficiencies above 30 %. [...]
