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.

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.

On a way to the market; Fully scalable Perovskite/Perovskite tandem solar modules

Light management, high-throughput laser interconnections and industrial coationg methods pave the way to the world’s first all perovskite tandem solar module - The team of T.T.Prof. U. Paetzold reports in Nature Energy

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.

Best contributed talk award at the 2021 Material Research Society (MRS) Fall Meeting

Doctoral student Ahmed Farag from the Institute of Microstructure Technology (IMT) received an award for the best contributed talk at the hybrid 2021 Materials Research Society (MRS) fall meeting in Boston. The award was given for his oral presentation on ‘’ Micrometer-Thick Solution Processed Perovskite Solar Cells on Industrial-Like Textured Si Substrates for Efficient Light Harvesting’’.

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.

Tenure-Track-Prof. Dr. Ulrich W. Paetzold appointed to the Tenure-Track-Professorship Next Generation Photovoltaics

Effective March 1st, 2021, Ulrich W. Paetzold has been appointed to the Tenure-Track-Professorship Next Generation Photovoltaics of the KIT Faculty of Electrical Engineering and Information Technology in Area III. Ulrich W. Paetzold and his interdisciplinary team develop and research new materials, future-oriented device architectures, and innovative manufacturing processes for perovskite photovoltaics. The enormous progress in perovskite research makes this material system a beacon of hope for high-performance and cost-effective solar cells.

Prize for the best PhD presentation at the OSA Advanced Photonics Congress

01.08.2019 - Doctoral student Raphael Schmager from the Institute of Microstructure Technology (IMT) received an award for the best student presentation at the OSA Advanced Photonics Congress in San Francisco. The award was given for his oral presentation on “Nanophotonic Perovskite Thin-Film Solar Cells by Thermal Nano-imprint Lithography” in the topical meeting on “Optical Devices and Materials for Solid Energy and Solid-state Lightning"

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.
