HZB-Highlights 2022 published

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.
- Electrocatalysts: New model for charge separation at the solid-liquid interfaceHydrogen is at the heart of the transition to carbon neutrality, as both an energy carrier and a reagent for green chemistry. However, large-scale production of hydrogen via electrolysis, as well as the production of many other chemical products, requires significantly cheaper and more efficient catalysts. A precise understanding of the electrochemical processes that take place at the interface between the solid catalyst and the liquid medium is highly useful for developing better electrocatalysts. In the journal Nature Communications, an European team has now presented a powerful model that determines charge separation at the interface, the formation of the electric double layer and local electric potential variations, and the resulting influence on the catalytic activity.
- Environmental Chemistry at BESSY II: Radicals in waterwaysHow do radicals form in aqueous solutions when exposed to UV light? This question is important for health research and environmental protection, for example with regard to the overfertilisation of water bodies by intensive agriculture. A team at BESSY II has now developed a new method of investigating hydroxyl radicals in solution. By using a clever trick, the scientists gained surprising insights into the reaction pathway.
- Theory meets practice – We’re heading back to HTW Berlin!The HZB’s BIPV consultancy office (BAIP) is once again coordinating and delivering the lecture series “Building-Integrated Photovoltaics”.
