Mechanisms and modeling of blue OLED degradation
Dr. Chris Giebink – University of Michigan
Vasilis Georgakopoulos - Ph.D Student, Fluxim/ University of Bayreuth
Dr. Matthias Diethelm – Fluxim (Host)
📅 Tuesday, May 12, 2026
🕒 3pm CEST (9 am EDT)
For our 19th webinar, we are pleased to welcome our invited guest, Dr. Chris Giebink, Professor at the University of Michigan. His research lies at the intersection of optics and electronics, with a focus on charge transport, excited states, and light-matter interaction in organic semiconductors for applications such as OLEDs and solar cells.
He will be presenting:
Mechanisms and modeling of blue OLED degradation
In this talk, Dr. Giebink will discuss the key physical processes driving degradation in blue OLEDs, including exciton-induced damage, charge imbalance, and defect formation. Drawing on both experimental and modeling approaches, he will provide insights into how degradation mechanisms can be identified, quantified, and ultimately mitigated to improve device lifetime and performance.
Following on from Chris will by Ph.D Student Vasilis Georgakopoulos who will be giving a talk based on his Ph.D project with Fluxim.
The webinar will be hosted by Matthias Diethelm.
Date & Time: Tuesday, 12 May 2026, 15:00–16:00 (CEST) (9am EDT)
This webinar is a must-attend for researchers from both industry and academia working on OLED devices, display technologies, and device stability.
We look forward to seeing you there!
Invited Speakers
Dr. Chris Giebink
Dr. Chris Giebink is a professor at the University of Michigan and head of the Applied Optoelectronics and Photonics Lab. His work explores the fundamental physics of organic semiconductors, including charge transport, excited states, and light-matter interaction, with applications in OLEDs, solar energy, and other optoelectronic devices.
Vasilis Georgakopoulos
Vasileios Georgakopoulos Paltidis is a PhD candidate in Computational Physics at the University of Bayreuth and an R&D scientist at Fluxim AG. His work focuses on display technologies, with expertise in electrical and optical characterization, as well as device modelling of organic light-emitting diodes (OLEDs).
He has strong experience in multi-physics simulation, software development, and the validation of models through experimental data. Vasileios has also contributed to collaborative projects between academia and industry, with results disseminated through publications and conference presentations.
Dr. Matthias Diethelm
Matthias is an R&D Scientist at Fluxim. His appointment at Fluxim follows a distinguished academic journey, most recently as a Postdoctoral Researcher at Empa and the University of Oxford, where he advanced key research in CIGS and perovskite photovoltaics. With a PhD from EPFL earned through research at Empa, Matthias has significantly contributed to our understanding of ion-influenced optoelectronics, OLED technologies and photovoltaics, demonstrated through numerous impactful publications.
