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.

K. Geistert
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.

Preis für die beste Doktorandenpräsentation auf dem 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

Tandemsolarmodule: Mehr Strom aus dem Doppelpack

Da sich der Wirkungsgrad handelsüblicher Solarzellen nur noch begrenzt steigern lässt, haben Forscherinnen und Forscher Perowskit-Halbleiter mit Halbleitern aus Kupfer, Indium, Gallium und Selen (CIGS) zu Tandemsolarzellen kombiniert. Dadurch werden Wirkungsgrade von über 30%, unter Erhaltung aller Vorteile der Dünnschicht-Technologie, erreicht.

Tobias Abzieher, KIT
Neuartige Transportschicht ermöglicht hocheffiziente Perowskit-Solarzellen

Zur Nutzung der Sonne als unerschöpfliche Energiequelle spielt die Photovoltaik eine entscheidende Rolle. Forschern am LTI auf dem KIT Campus ist es gelungen ein neueartige, hocheffiziente Lochleiterschicht aus Nickeloxid zu entwicklen, die Perowskit-Solarzellen zu Rekordeffizienzen verhilft.
