Resume of Career

Martin Stolterfoht joined the Department of Electronic Engineering at the Chinese University of Hong Kong (CUHK) as a VC Early Career Associate Professor in August 2023. He completed his Master’s degree in Physics at the University of Graz, Austria in 2012 and obtained his Ph.D. at the University of Queensland, Australia in 2016 with a focus on charge transport and recombination in organic photovoltaics. From 2016 to 2019 he was a Postdoctoral Researcher at the University of Potsdam (UP), Germany with his primary research revolving around a fundamental investigation of recombination in perovskite solar cells through advanced optical and electro-optical characterization techniques and numerical simulations.

From November 2019 until August 2023, he led the Potsdam Perovskite Research Group at UP, and in April 2022 he became a Heisenberg fellow funded by the German Research Foundation. During his career, he also visited the National Renewable Energy Laboratory (NREL) in the USA and the University of Oxford in the UK for extended research stays.

Martin has acquired funding for 8 major joint and individual research grants. He has authored/co-authored 86 publications in renowned journals including Science and Nature and presented 35 contributed and invited conference talks. Martin has advised 3 postdoctoral researchers, 8 Ph.D. students, 2 Master’s students, and 6 Bachelor students.

Current Research Interests

Martin aims to bring the operational stability of perovskite solar cells to an industrial level (>20 years lifetime) via a global characterization of mobile ion-induced efficiency losses and their impact on device degradation. He also strives to develop a new generation of high-performance perovskite-based multijunction solar cells such as silicon/perovskite and all-perovskite and organic/perovskite tandem cells. His objective also includes establishing a fundamental description of thin film solar cell operation, charge transport, and recombination processes from picoseconds to steady-state through electro-optical measurements and numerical modeling.

Keywords: Perovskite and organic solar cells, perovskite-based tandem solar cells, optoelectronic devices, charge transport and recombination, ionic transport, device simulations, optoelectronic and spectroscopic thin film characterization
