Welcome to the Helmholtz-Zentrum Berlin

At the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) we explore materials and complex material systems that help to face current and future challenges, such as the energy transition - “Energiewende”. One of the HZB’s research emphases is on materials for thin-film photovoltaics and for the conversion of solar energy into chemical energy carriers (e.g. molecular hydrogen).

To be able to study material structures and processes in detail, the HZB operates two separate large-scale research facilities – the neutron source BER II and the synchrotron radiation source BESSY II – used by some 3,000 guest scientists from all around the World every year. At both facilities, HZB teams have developed in some cases unparalleled instruments and are continuing to work on increasing their measurement precision to allow for new insights to be gleaned.

The HZB is a member of the Helmholtz Association and co-founder of the Competence Centre for Thin-Film and Nanotechnology for Photovoltaics Berlin (PVcomB), whose mission it is to promote the technology transfer to industry.

    Registration now open! Summer School Quantsol

    The International Summer School Quantsol will inform on basics in photovoltaics and solar energy conversion.

    For the eighth time already young solar energy researchers are invited to attend the International Summer School on Photovoltaics and New Concepts of Quantum Solar Energy Conversion (Quantsol). The school will be held from September 6th to 13th, 2015 in Hirschegg, Kleinwalsertal, Austria. The school is organized by the Helmholtz-Zentrum Berlin together with the Technical University of Ilmenau. Application can be submitted through the school’s homepage until May 31st, 2015. [...].

    Neutrons and X-rays show how to prepare durable tooth cement

    There are many ways to mix cements for tooth fillings, but it can be difficult to tell which way works best. Now, a team of scientists from Copenhagen, Denmark, has come up with an answer: They used neutron imaging and x-ray-microtomography at HZB to analyze fillings with glass ionomere cements, prepared by different methods. Their results, now published in  Scientific Reports, demonstrate how much the order of mixing steps matters to obtain a nearly homogenous filling without large liquid-filled pores which reduce stability.

    The BER II neutron source is back in operation and available for experiments following the interruption in availability

    Maintenance work has been successfully concluded – the High-Field Magnet has successfully attained 26 tesla in initial testing. New scientific experiments have become possible.

    Berlin, February 2015: following conclusion of more than a of year of repairs and refurbishing, the BER II neutron source will shortly be available to its international user group again. The facility was powered up on Wednesday, February 18 and attained its nominal power level of 9,5 megawatts. Scientists of HZB are meanwhile preparing the measurement equipment so that experimental work can resume following a brief start-up period. [...].
