Light Technology Institute
Nanotechnology, visual ergonomics, materials science and system design – these are a few examples from the wide spectrum of light technology research projects and services at our institute.
We are looking forward to an exciting exchange of ideas in productive joint projects and hope you enjoy visiting our website.
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.
In nature plant fragrances attract insects. But they are also used in industry, for example in the production of perfumes and aromas. In order to reliably, quickly and objectively distinguish the scents of mint, researchers at the Karlsruhe Institute of Technology (KIT) have developed an electronic nose with an artificial sense of smell in an interdisciplinary collaboration: With high precision, it can recognize different types of mint - making it suitable for applications ranging from pharmaceutical quality control to the observation of mint oil as an environmentally friendly bioherbicide.
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.more
LTI startup Digital Power Systems (DPS) will be exhibiting at the digital Hannovermesse from April 12-16, 2021.
In this context, an information film on the technology has also been created: Rethinking Power Suppliesmore
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.
Thermoelectric generators, or TEGs, convert ambient heat into electrical energy. They provide a maintenance-free, environmentally friendly and self-sufficient power supply for the ever-growing number of sensors and devices for the Internet of Things (IoT) and a way to recover waste heat. Scientists at the Karlsruhe Institute of Technology (KIT) have now developed three-dimensional component architectures with novel, printable thermoelectric materials. These could represent a milestone for the use of low-cost TEGs. They report their results in the journals npj Flexible Electronics (DOI: 10.1038/s41528-020-00098-1) and ACS Energy Letters (DOI: 10.1021/acsenergylett.0c02159).
