At the end of 2019, the Berlin neutron source BER II was shut down as scheduled. To ensure that the high-quality instruments can continue to be used for research, they are moving to suitable neutron sources in Germany and abroad. Now, another move has been agreed upon: The Very Small Angle Scattering Instrument (VSANS) will find a new home at the Breazeale Research Reactor at Penn State University, USA, in spring 2022.

At Penn State University, the Radiation Science & Engineering Center (RSEC) operates the Breazeale reactor, which produces neutrons for research. An expansion is now planned there to accommodate the new, very large VSANS instrument.

VSANS stands for Very Small-Angle Neutron Scattering, i.e. the scattering of neutrons at very small scattering angles. This method enables insights into colloidal systems and soft matter, but also into glasses, biomimetic structural proteins, microemulsions, flexible electronics and many other questions, from physics to biology.

"Our goal is that our excellent instruments will continue to be available for research and innovation after BER II is shut down. We are therefore very pleased that the VSANS is being reinstalled at the Breazeale reactor", says Roland Steitz, HZB.  This means that the HZB experts have now found a new location for almost all neutron instruments.

"The Breazeale reactor at the Penn State RSEC will be the only university research reactor with a SANS facility in the United States," says Kenan Ünlü, director of the RSEC and professor of nuclear engineering.

    World record back at HZB: Tandem solar cell achieves 32.5 percent efficiency
    The current world record of tandem solar cells consisting of a silicon bottom cell and a perovskite top cell is once again at HZB. The new tandem solar cell converts 32.5 % of the incident solar radiation into electrical energy. The certifying institute European Solar Test Installation (ESTI) in Italy measured the tandem cell and officially confirmed this value which is also included in the NREL chart of solar cell technologies, maintained by the National Renewable Energy Lab, USA.

    On the way to mass production: perovskite silicon tandem cells
    In order to transfer tandem solar cells from laboratory scale to production, HZB is cooperating with the solar module manufacturer Meyer Burger, which has great expertise in heterojunction technology (HJT) for silicon modules. Within the framework of this cooperation, mass production-ready silicon bottom cells based on heterojunction technology are to be combined with a top cell based on perovskite technology.
