HZB-Highlights 2022 published

© HZB/M.Setzpfand

The Highlights 2022 report on a selection of the most important research results and events at HZB.

This year, the cyber attack made it much more difficult to compile the highlights 2022. But now it's done! One focus in this report is energy research, in which HZB is extraordinarily successful, from basic research to technology transfer. In 2022, HZB teams developed tandem solar cells with record efficiencies, and there was great progress in research on batteries and "green" hydrogen as well. In addition, HZB further expanded its collaborations with industrial partners fostering innovation in the solar industry in Europe. Selected research results from the fields of information and matter provide insights into the diversity of research at HZB and at our X-ray source BESSY II. The report ends with facts, figures, personalia, a short report on the Diversity Charter and a review of special events such as the visit of the swedish King.

    14 parameters in one go: New instrument for optoelectronics
    An HZB physicist has developed a new method for the comprehensive characterisation of semiconductors in a single measurement. The "Constant Light-Induced Magneto-Transport (CLIMAT)" is based on the Hall effect and allows to record 14 different parameters of transport properties of negative and positive charge carriers. The method was tested now on twelve different semiconductor materials and will save valuable time in assessing new materials for optoelectronic applications such as solar cells.

    Sodium-ion batteries: How doping works
    Sodium-ion batteries still have a number of weaknesses that could be remedied by optimising the battery materials. One possibility is to dope the cathode material with foreign elements. A team from HZB and Humboldt-Universität zu Berlin has now investigated the effects of doping with Scandium and Magnesium. The scientists collected data at the X-ray sources BESSY II, PETRA III, and SOLARIS to get a complete picture and uncovered two competing mechanisms that determine the stability of the cathodes.

    BESSY II: Molecular orbitals determine stability
    Carboxylic acid dianions (fumarate, maleate and succinate) play a role in coordination chemistry and to some extent also in the biochemistry of body cells. An HZB team at BESSY II has now analysed their electronic structures using RIXS in combination with DFT simulations. The results provide information not only on electronic structures but also on the relative stability of these molecules which can influence an industry's choice of carboxylate dianions, optimizing both the stability and geometry of coordination polymers.
