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.

    Spectacular transport: Undulator moved to the electron storage ring BESSY II

    A worldwide unique undulator developed at Helmholtz-Zentrum Berlin (HZB) was installed in the storage ring BESSY II on September 20, 2018. It supplies the "Energy Materials In-Situ Lab EMIL" with the hard X-ray light from BESSY II. The transport of the six-ton device was spectacular: several cranes were used to transport the undulator just a few hundred meters from the production building to the storage ring. [...].

    Patented nanostructure for solar cells: Rough optics, smooth surface

    Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem. [...].

    2.8 Mio Euro Funding for preparing perovskite solar cells for high volume manufacturing

    HZB participates in a new consortium for Perovskite solar technology that is led by Oxford PV Germany GmbH. The consortium is funded by the German Ministry of Economics and Energy with 2.8 Million Euros and aims to further demonstrate the manufacturability of perovskite-silicon tandem solar cells. [...].

    Printing solar cells and organic LEDs

    Humboldt-Universität zu Berlin and Helmholtz-Zentrum Berlin form a joint lab and research group “Generative production processes for hybrid components”.

    Solar cells, LEDs and detectors made of organic and hybrid semiconductors can nowadays be simply printed out, even together with teensy nanostructures that make them function better. The development of low-cost printing methods for electronic and optoelectronic components is at the centre of things for the new joint research group and the joint laboratory of the Helmholtz-Zentrum Berlin (HZB) and Humboldt-Universität zu Berlin (HU).
