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.

    MXene for energy storage: More versatile than expected
    MXene materials are promising candidates for a new energy storage technology. However, the processes by which the charge storage takes place were not yet fully understood. A team at HZB has examined, for the first time, individual MXene flakes to explore these processes in detail. Using the in situ Scanning transmission X-ray microscope 'MYSTIIC' at BESSY II, the scientists mapped the chemical states of Titanium atoms on the MXene flake surfaces. The results revealed two distinct redox reactions, depending on the electrolyte. This lays the groundwork for understanding charge transfer processes at the nanoscale and provides a basis for future research aimed at optimising pseudocapacitive energy storage devices.
