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.

    High Field Magnet at BER II: Insight into a hidden order

    A specific uranium compound has puzzled researchers for thirty years. Although the crystal structure is simple, no one understands exactly what is happening once it is cooled below a certain temperature. Apparently, a “hidden order” emerges,  whose nature is completely unknown.Now physicists have characterised this hidden order state more precisely and studied it on a microscopic scale. To accomplish this, they utilised the High-Field Magnet at the HZB that permits neutron experiments to be conducted under conditions of extremely high magnetic fields. [...].

    Missing link between new topological phases of matter discovered

    HZB-Physicists at BESSY II have investigated a class of materials that exhibit characteristics of topological insulators. During these studies they discovered a transition between two different topological phases, one of which is ferroelectric, meaning a phase in the material that exhibits spontaneous electric polarisation and can be reversed by an external electric field. This could lead to new applications such as switching between differing conductivities. [...].

    Goodbye Paper Cups: Starting Monday, coffee in the Wannsee canteen will only be served in reusable cups

    As many as 150 coffee-to-go cups are used every day in the Wannsee canteen. These cups cannot be reasonably recycled, and instead end up as land fill. Now, the canteen is putting an end to this wastage. As of the 16th of October, coffee to go can only be bought in the new HZB returnable cups (available for 5 euros at the checkout) or served in your own cup, which you bring from home.

    New: Campusblog at HZB

    An anecdote from the canteen, a curious lab photo, and an exciting encounter – there are many stories which just need to be written up . Now we have the Campus Blog of the Helmholtz Zentrum Berlin for this. You will read in the blog, for example, that a HZB staffer cleared paths with a chain saw the whole night long during the Xavier storm, and other interesting stories. [...].

    Invitation to HySPRINT – Industry Day “New Frontiers in PV Research: Emerging Perovskite Semiconductors”

    On 13 October, Helmholtz-Zentrum Berlin will be hosting its first Industry Day on the topic of Perovskite Solar Cells. Following a recap of the current state of research and development and the future potential of perovskite solar cells, participants from industry will be able to give a brief presentation to show their company’s interest in the field. Intensive discussions during the Industry Day will be the starting point for future cooperation. [...].
