Researchers at the Institute of Lighting Technology have succeeded in integrating a 2D temperature sensor array by printing it onto the heat sink of a processor. The array comprises 396 sensor pixels, enabling high spatial resolution and detailed representation of the processor's temperature distribution. Based on this information, the reliability and performance of computer systems can be further optimized. This form of monitoring also offers new possibilities in computer security. By fully integrating the sensor into the system, modifications to the system can be minimized.

The optics and photonics student group here at KIT, Optics Students Karlsruhe (OSKar), received the 2023 SPIE Presidential Award for Outstanding Student Chapter, at the SPIE Optics & Photonics conference in San Diego. SPIE President Bernard Kress reported that the chapter stood out because of its breadth of activities, including International Day of Light (IDL) observations, industry visits, and social and networking events. Having celebrated their 10th anniversary in 2022, OSKar continues to have an active presence here at LTI and the university at large.

Mr. M.Sc. Raphael Pesch was awarded the SEW EURODRIVE STIFUNG 2022 Study Prize on May 11, 2023, which carries a prize money of 2500 euros. This award was bestowed upon him in recognition of his outstanding academic performance and master's thesis titled "Deformation Sensing and Object Identification with Elastochromic Photonic Materials“. The master's thesis was conducted during his stay at Massachusetts Institute of Technology in collaboration with Prof. Dr. Mathias Kolle (MIT, LBPE) and Prof. Dr. Ulrich Lemmer (KIT, LTI). We congratulate the recipient on this achievement and wish him continued success in his doctoral studies at the Light Technology Institute.

X-ray detectors are widely used in medicine, industry and science. Perovskite semiconductor technology, which has already been successfully used in solar cells, also enables large-area and mechanically flexible detectors. Researchers at the Karlsruhe Institute of Technology (KIT) have now produced the semiconductor layers by inkjet printing in a new manufacturing process and realized the detector geometry by an origami-inspired folding method.

The results are published in the journal npj Flexible Electronics.

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.
