Invited Speakers
Prof. Martin Stolterfoht
Prof. Martin Stolterfoht is an Early Career VC Associate Professor in the Electronic Engineering Department of The Chinese University of Hong Kong (CUHK), a position he commenced in August 2023. In 2024 and 2025, he was recognized as a Highly Cited Researcher by Clarivate Analytics. Before this appointment at CUHK, he was awarded the prestigious Heisenberg fellowship from the German Research Foundation in 2022. Before that, he led the Potsdam Perovskite Research Group at the University of Potsdam, Germany, from 2019 to 2023. During this time, he also received the Postdoc Prize of the State of Brandenburg for outstanding scientific work. He earned his Ph.D. from the University of Queensland, Australia, in 2016. In his career, he acquired funding for 17 joint and individual research grants as PI or PC. He co-authored >100 peer-reviewed publications in renowned journals, including Science and Nature. In Hong Kong, he also co-founded SolarSense Technologies Limited. At CUHK, he currently leads the Photon Energy Conversion Lab (peclab.net), which focuses mainly on understanding and enhancing the stability of perovskite-based solar cells, but also X-ray detectors, organic solar cells, IoT, and biomedical sensors.
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.
