Marko Jošt, Steve Albrecht and Bernd Rech, researchers at the Helmholtz-Zentrum Berlin (HZB) and the Technische Universität Berlin (TUB) receive a rare award today, 19 December 2018. In the slovenian Grand Hall of Presidential Palace, the Slovenian President, Borut Pahor, presents them with the "Apple of Inspiration". It honours achievements in culture, science, sport and society. The Berlin scientists are the first foreigners who receive the prize together with colleagues from the University of Ljubljana.

The teams from Ljubljana and Berlin are honored for their long-standing collaboration, which has led to milestones in the development of perovskite solar cells. This is documented, for example, by a joint publication in the renowned journal Energy and Environmental Science on an efficiency record for a monolithic tandem solar cell made of silicon and perovskite layers.

Dr. Marko Jošt, who was the first author of the study and contributed significantly to the joint results, received his doctorate both at the University of Ljubljana and at the TUB. Today he is a postdoctoral researcher at the HZB.

The excellent international cooperation not only inspires young scientists in Slovenia, but also contributes to further strengthening research into alternative energy sources, according to the Slovenian government. "International cooperation and the results achieved are of great importance for society. They help to find solutions for a sustainable energy turnaround and thus also to fight against climate change and thus secure our livelihoods".

Prof. Steve Albrecht, head of a BMBF-funded junior research group at the HZB and junior professor at the TUB, is the coordinator of the mentioned study. In cooperation with the Helmholtz Innovation Lab HySPRINT and the Photovoltaic Competence Centre PVcomB, he develops and analyses the very complex tandem cells with the aim of leading them to a greater technological maturity.

Prof. Bernd Rech, solar researcher and currently acting scientific director of the HZB, initiated the German-Slovenian cooperation together with the Slovenian professor Marko Topic. Among other things, he was a visiting professor at the University of Ljubljana in 2014. The close cooperation continues to this day. Marko Jost, the joint doctoral student at the time, is now a postdoctoral researcher in Steve Albrecht's group.

    Cool vaccines in rural Kenya: solar solution has been awarded by UN
    In May 2026, Tabitha Awuor Amollo is spending some weeks as a guest scientist at HZB, analysing perovskite thin films at BESSY II. The Kenyan physicist from Egerton University, Nairobi, was recently recognised for her achievements in research and teaching. For the development of a solar-powered refrigeration system for use in rural health centres, she  has been awarded the 2026 Organization for Women in Science for the Developing World (OWSD)-Elsevier Foundation Award. An interview on exceptional projects and daily struggles of a scientist. Questions were asked by Antonia Rötger.

    BESSY II: How intrinsic oxygen shortens the lifespan of solid-state batteries
    Although solid-state batteries (SSBs) demonstrate high performance and are intrinsically safe, their capacity currently declines rapidly. A team from the TU Wien, Humboldt-University Berlin and HZB has now analysed a TiS₂|Li₃YCl₆ solid-state half-cell in operando at BESSY II using a special sample environment that allows for non-destructive investigation under real operating conditions. Data obtained by combination of soft and hard X-ray photoelectron spectroscopy (XPS and HAXPES) revealed a new degradation mechanism that had not previously been identified in solid-state batteries. They have gained some surprising insights, particularly regarding the harmful role played by intrinsic oxygen. This study provides valuable information for improving design and handling of such batteries.

    Too old for research at 60? From nuclear physics to papyrus research
    A career in science can be personally fulfilling. However, this also means accepting the unpredictable: research topics may no longer receive funding, and laboratories may close. Heinz-Eberhard Mahnke experienced this first-hand when he had to seek new challenges in his early 60s. Today, the 81-year-old is still active in research, using non-destructive measurement methods to examine ancient artefacts of inestimable cultural value. Antonia Rötger spoke with this extraordinary researcher, whose curiosity and drive are truly inspiring.
