Light Technology Institute

Current information on studying and teaching in the context of COVID

Until further notice, there will be no face-to-face lectures on campus. The LTI lectures are therefore all offered online. Please inform yourself on ILIAS. We will inform you on ILIAS and on this page about further developments.

Further information can be found on the official ETIT Homepage: Coronavirus - Information and Recommendations of the KIT Faculty ETIT

Despite the Corona-related restriction, we continue to offer final thesis at LTI. These can be started at any time under compliance with the hygiene requirements. If you are interested, please get in touch with the contact person by email or phone to make an appointment.

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.

Startup Digital Power Systems (DPS) exhibits at the Hanovermesse

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 Supplies

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

Effective March 1st, 2021, Ulrich W. Paetzold has been appointed as a junior professor 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.

Energy harvesting through printed thermoelectric generators

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).

PD Dr.-Ing. Alexander Colsmann appointed as associate professor

With effect from November 2, 2020, Alexander Colsmann was awarded the title of "Extraordinary Professor" by the KIT President. KIT thus honors his successful activities in research and teaching. Mr. Colsmann represents the research area "Organic Optoelectronics". He heads a research group at the Materials Science Center for Energy Systems (MZE). We are pleased about this award and wish Mr. Colsmann the best.

Michael Heidinger Achieves 1st Place of the KIT Technology Transfer Prize
