Our next Fluxim Research Webinar is coming up next Tuesday, June 9. For the 20th edition of the series, we are focusing on one of the key challenges in perovskite solar cell research: understanding how mobile ions and shallow traps contribute to degradation losses.

Agenda
• Invited talk by Prof. Martin Stolterfoht
The role of mobile ions and shallow traps in governing degradation losses in perovskite solar cells

• Follow-up talk by Dr. Matthias Diethelm
Ion parameter extraction in perovskite solar cells

• Q&A
Your chance to ask questions about the presentations

• Webinar host
Dr. Matthias Diethelm, Fluxim AG

Date & Time
Tuesday, June 9, 2026
10:00am-11:00am CEST
4:00pm-5:00pm Hong Kong Time

Invited Speaker
Prof. Martin Stolterfoht, The Chinese University of Hong Kong
Prof. Martin Stolterfoht is an Early Career VC Associate Professor in the Department of Electronic Engineering at The Chinese University of Hong Kong (CUHK). He leads the Photon Energy Conversion Lab, where his group focuses on understanding and enhancing the stability of perovskite-based solar cells, alongside related optoelectronic devices such as X-ray detectors, organic solar cells, IoT devices, and biomedical sensors.

In this talk, Prof. Stolterfoht will discuss the role of mobile ions and shallow traps in degradation losses in perovskite solar cells. The webinar will address topics central to perovskite device stability, including ion migration, shallow traps, recombination losses, and the physical mechanisms that limit long-term performance.

Fluxim Speaker and Host
Dr. Matthias Diethelm, R&D Scientist, Fluxim AG
Dr. Matthias Diethelm is an R&D Scientist at Fluxim. His research background includes postdoctoral work at Empa and the University of Oxford, as well as a PhD from EPFL based on research at Empa. His work has contributed to the understanding of ion-influenced optoelectronics, OLED technologies, and photovoltaics.

In the follow-up talk, Dr. Diethelm will present:
Ion parameter extraction in perovskite solar cells

This webinar is relevant for researchers and engineers working on perovskite solar cells, tandem photovoltaics, device stability and degradation, ion migration, shallow traps, recombination losses, optoelectronic characterization, and device modelling and simulation.

We look forward to seeing you next Tuesday, June 9, at 10:00am CEST / 4:00pm Hong Kong Time.
