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.

    Newsletter and Highlightreport

    Exactly twenty years ago, BESSY II went into operation. In the current September newsletter, which we are sending out this week, we present the anniversary website, report on the new highlight report 2017 and on successes in technology transfer. Have you already registered for the newsletter? Here is the registration link. [...].

    Atoosa Meseck is a professor of accelerator physics at the University of Mainz

    On 1 September 2018, Johannes Gutenberg University Mainz appointed Atoosa Meseck to the joint professorship “Accelerator physics – collective effects and nonlinear beam dynamics”. Prof. Dr. Atoosa Meseck is researching at HZB into novel concepts for undulators, as are indispensable for producing high brightness synchrotron radiation. Among other things, she is developing undulator concepts for the successor facility BESSY III, for which the concept is currently being developed at HZB. [...].

    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. [...].
