    New Helmholtz Young Investigator Group at HZB on perovskite solar cells
    Silvia Mariotti starts building up the new Helmholtz Young Investigator Group ‘Perovskite-based multi-junction solar cells’. The perovskite expert, who was previously based at Okinawa University in Japan, aims to advance the development of multi-junction solar cells made from different perovskite layers.

    Optical innovations for solar modules - which are the most promising?
    In 2023, photovoltaic systems generated more than 5% of the world’s electrical energy and the installed capacity doubles every two to three years. Optical technologies can further increase the efficiency of solar modules and open up new applications, such as coloured solar modules for facades. Now, 27 experts provide a comprehensive overview of the state of research and assess the most promising innovations. The report, which is also of interest to stakeholders in funding and science management, was coordinated by HZB scientists Prof. Christiane Becker and Dr. Klaus Jäger.

    Perovskite solar cells: New Young Investigator Group funded by BMBF at HZB
    In the COMET-PV project, Dr Artem Musiienko aims to significantly accelerate the development of perovskite solar cells. He is using robotics and AI to analyse the many variations in the material composition of tin-based perovskites. The physicist will set up a Young Investigator Group at HZB. He will also have an affiliation with Humboldt University in Berlin, where he will gain teaching experience in preparation for a future professorship.

    HZB Sets New World Record for CIGS Perovskite Tandem Solar Cells
    Combining two semiconductor thin films into a tandem solar cell can achieve high efficiencies with a minimal environmental footprint. Teams from HZB and Humboldt University Berlin have now presented a CIGS-perovskite tandem cell that sets a new world record with an efficiency of 24.6%, certified by the independent Fraunhofer Institute for Solar Energy Systems.
