If you look for us in person, you will find us at both the Institute of Microstructure Technology and the Light Technology Institute at the Karlsruhe Institute of Technology (KIT). Enjoy reading about our work and always feel invited to contact us. Do not forget to check out our latest updates and news @PeroTaskforce.

Tenure-Track-Prof. Dr. Ulrich W. Paetzold

At the heart of a sustainable future, inexpensive electrical energy needs to be guaranteed to all people on this planet. Photovoltaics bear the potential to generate the required amount of electrical energy at low cost by harvesting the globally available and inexhaustible energy resource of the sun. Unfolding the full potential of next generation photovoltaic technologies by research, innovation, and academic education is our scientific mission and ambition.

Kristina Geistert Poster Award
Kristina Geistert receives the Poster Award at EU PVSEC-40 2023

We're thrilled to share that Kristina Geistert has received the Poster Award in the thematic area of 
“Thin Films and New Concepts” at the EU PVSEC-40 2023! Congratulations for her outstanding visual presentation on "Upscaling of Solution Processed Perovskite PV: Drying and Crystallization Dynamics of Slot-Die Coated Perovskite Solar Modules during Gas Quenching". In this work, Kristina and her colleagues demonstrate the fundamental interrelation between drying and crystallization dynamics during perovskite morphology formation and the quality of slot-die coated gas quenched polycrystalline perovskite thin films, reliably depositing high-quality perovskite thin film with a homogeneous morphology over a large area.

Ulrich W. Paetzold Receives ERC Consolidator Grant

T.T. Prof. Ulrich W. Paetzold has been awarded a highly endowed ERC Consolidator Grant from the European Research Council (ERC). He leads an international and highly interdisciplinary research group on new materials and processes for next generation photovoltaics. The ERC award will further strengthen his research on perovskite (tandem) photovoltaics. The proposed project aims to develop a radically new manufacturing process for high quality perovskite semiconductor that has the potential to overcome key challenges of perovskite thin film processing.

Thin-film photovoltaics: Efficient and versatile in a double pack

Stacking solar cells on top of each other increases efficiency. Researchers from the Perovskite Photovoltaics Taskforce, together with partners in the EU project PERCISTAND, have now produced perovskite/CIS tandem solar cells with an efficiency of almost 25 percent - the highest to date for this technology.

Ms. M.Sc. Kristina Geistert receives the 2020 Study Award of the SEW EURODRIVE FOUNDATION

Ms. M.Sc. Kristina Geistert was awarded the study prize of the SEW EURODRIVE STIFTUNG 2020 on 7.5.2021.
The award was given due to her outstanding study performance and master thesis on the topic "Production of perovskite solar cells based on non-hazardous volatile solvent systems". We congratulate the award winner and wish the PhD student at the Institute of Light Technology continued success.

Upscaling PV
All-evaporated Perovskite Solar Modules reaching efficiency > 18%

Upscaling perovskite photovoltaics from cell to module level with scalable processes is a key challenge. Researchers at IMT and LTI have now produced perovskite solar modules with almost no loss of scaling. They combine laser-scribed interconnection lines with the ease of co-evaporated perovskites.

Tandem solar modules: More power from the double pack

Since the efficiency of commercially available solar cells can only be increased to a limited extent, researchers have combined perovskite semiconductors with semiconductors made of copper, indium, gallium and selenium (CIGS) to form tandem solar cells. This achieves efficiencies of over 30%, while retaining all the advantages of thin-film technology.
