    BESSY II sheds light on how the internal compass is constructed in magnetotactic bacteria

    Bacteria exist in many shapes and with very different talents. Magnetotactic bacteria can even sense the earth’s magnetic field by making use of magnetic nanoparticles in their interior that act as an internal compass. Spanish teams and experts at Helmholtz-Zentrum Berlin have now examined the magnetic compass of Magnetospirillum gryphiswaldense at BESSY II. Their results may be helpful in designing actuation devices for nanorobots and nanosensors for biomedical applications. [...].

    Hidden talents: Converting heat into electricity with pencil and paper

    Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest of components: a normal pencil, photocopy paper, and conductive paint are sufficient to convert a temperature difference into electricity via the thermoelectric effect. This has now been demonstrated by a team at the Helmholtz-Zentrum Berlin. [...].

    User experiment at BESSY II: Complex tessellations, extraordinary materials

    Simple organic molecules form complex materials through self-organization

    An international team of researchers lead by the Technical University of Munich (TUM) has discovered a reaction path that produces exotic layers with semiregular structures. These kinds of materials are interesting because they frequently possess extraordinary properties. In the process, simple organic molecules are converted to larger units which form the complex, semiregular patterns. With experiments at BESSY II at Helmholtz-Zentrum Berlin this could be observed in detail. [...].

    Perovskite solar cells: mesoporous interface mitigates the impact of defects

    The nominal cell operating life of perovskite solar cells is strongly influenced by their inner architecture.This was shown by two scientists at the Helmholtz-Zentrum Berlin and the Technical University of Munich. They combined experiments with numerical simulations in order to explain this observation. [...].

  • Simplified cross-section of a perovskite solar cell: the perovskite layer does not cover the entire surface, but instead exhibits holes. The scientists could show that a protective layer is being built up which prevents short circuits. Picture: HZB15.01.2018

    Perovskite solar cells: perfection not required!

    Experiments at BESSY II reveal why even inhomogeneous perovskite films are highly functional 

    Metal-organic perovskite layers for solar cells are frequently fabricated using the spin coating technique. If you follow the simplest synthesis pathway and use industry-relevant compact substrates, the perovskite layers laid down by spin coating generally exhibit numerous holes, yet attain astonishingly high levels of efficiency. The reason that these holes do not lead to significant short circuits between the front and back contact and thus high-rate charge carrier recombination has now been discovered by a HZB team headed by Dr.-Ing. Marcus Bär in cooperation with the group headed by Prof. Henry Snaith (Oxford Univ.) at BESSY II. [...].

    User research at BER II: Lupin roots observed in the act of catching water from soil – so far too quick for 3D views

    Lupins not only produce colourful blossoms but also nutritious beans rich in proteins. Just how these plants draw water approaching their roots in soil has now for the first time been observed in three dimensions by a University of Potsdam team at the HZB-BER II neutron source in Berlin. To accomplish this, they worked with the HZB imaging group to improve the temporal resolution of neutron tomography more than onehundred-fold so that a detailed 3D image was generated every ten seconds. This ultrafast neutron tomography is generally suitable as well for analyses of dynamic processes in porous materials. [...].

    Three-dimensional graphene: experiment at BESSY II shows that optical properties are tuneable

    An international research team has for the first time investigated the optical properties of three-dimensional nanoporous graphene at the IRIS infrared beamline of the BESSY II electron storage ring. The experiments show that the plasmonic excitations (oscillations of the charge density) in this new material can be precisely controlled by the pore size and by introducing atomic impurities. This could facilitate the manufacture of highly sensitive chemical sensors. [...].

    How to increase efficiencies of ultrathin CIGSe solar cells

    Nanoparticles at the back help harvesting light.

    Ultrathin CIGSe solar cells need much less rare earth elements and energy for production. Unfortunately, they are much less efficient too. Now a team at HZB together with a group in the Netherlands has shown how to prevent the absorption loss of ultrathin CIGSe cells.  They designed  nanostructured  back contacts for light trapping and could achieve a new record value of the the short circuit current density reaching nearly the best values for thicker CIGSe-cells.

Ever since, HZB has been building the system that will bring X-ray beams all the way from BESSY II to the EMIL apparatuses. Until the BESSY light is fully available, the scientists have been working with X-rays from a conventional laboratory source. Now, the beamline operators have succeeded in guiding the X-rays from Undulator UE48 in the BESSY II experimental hall to the CAT experiment in the EMIL laboratory.

    Methods at BESSY II: Versatile cross-correlator for ultrafast X-ray experiments

    Particularly in the soft X-ray range experimentalists are lacking a broadband method to correlate ultrashort X-ray and laser pulses in space and time. Only recently, a team from Helmholtz-Zentrum Berlin and the University of Potsdam was able to achieve this by utilizing a standard molybdenum-silicon (Mo/Si) multilayer mirror at the FemtoSpeX facility at BESSY II. They use femtosecond laser pulses to modulate the multilayer period under the Bragg condition on a sub-picosecond up to nanosecond timescale which in turn strongly affects the mirror’s X-ray reflectivity. The presented Mo/Si cross-correlator works for the soft up to the hard X-ray regime as well as for a broad range of laser pump wavelengths (mid-IR to UV) and renders this technique as an easy to implement and versatile timing tool for various synchrotron- and lab-based pump-probe experiments. The results are published in the journal of "Structural Dynamics". [...].
