Yungui Li

Dr. Yungui Li serves as a Group Leader at the Max Planck Institute for Polymer Research (MPIP) in Mainz, Germany, leading research on fundamental photophysical properties of organic semiconductors and their application in optoelectronic devices.

His academic background includes:

• B.Sc. from Huazhong University of Science and Technology (2012)
• M.Sc. from Huazhong University of Science and Technology (2015), completed in collaboration with PSA Group and Paris-Sud University
• Ph.D. from TU Dresden (2019) under Prof. Sebastian Reineke and Prof. Karl Leo, focusing on photon generation/dissipation in OLEDs

The Li Research Group investigates ultrafast exciton kinetics—including radiative and non-radiative processes—at molecular levels using transient absorption and time-resolved photoluminescence spectroscopy. Their work targets operational stability and efficiency gains in OLEDs, organic solar cells, and organic lasers by bridging fundamental photophysics with device engineering. Current emphases include thermally activated delayed fluorescence, room-temperature phosphorescence, and nanostructure design for white OLEDs.

Analysis of Dr. Li's 2019-2021 publications reveals consistent focus on overcoming efficiency barriers in organic optoelectronics. Key themes include minimizing non-radiative losses in triplet emitters, optimizing optical outcoupling in broad-recombination OLEDs, and developing photostable conjugated polymers. His collaborative work spans materials synthesis, device physics, and computational modeling, demonstrating interdisciplinary approaches to commercialization challenges in organic electronics.
