Dr. Jeremy HIEULLE

Jeremy Hieulle is a Research Scientist, and the Principal Investigator of the research project LION funded by the Luxembourg National Research Fund (FNR). He is a member of the Scanning Probe Microscopy Laboratory group in the team Surface & Interface Physics led by Professor Alex Redinger in the Department of Physics and Materials Science of the University of Luxembourg.

His scientific activities are focused on providing a better understanding of the fundamental properties of perovskite absorbers for photovoltaic applications. His research goal is to shine a light on the physical mechanisms hidden behind the light-induced degradation of perovskite absorbers. Unraveling the key parameters affecting the stability of perovskite materials could open the way to new strategies to mitigate degradation processes, bringing us a step forward to the commercialization of clean energy perovskite-based solar cells.

Tutorials of Experimental Physics, for first-year bachelor students.

Since he arrived at the University of Luxembourg, he has been involved in several teaching and outreach activities. In particular, he has participated in the Open Days of the University of Luxembourg, as well as the Science Festival in 2021. More recently, he joined the Scienteens lab, where he has participated in the organization of renewable energy workshops for high-school students in Luxembourg.

Seal of Excellence delivered by the European Commission, as the institution managing Horizon 2020, for project proposal 835399, MAGNUM (Magnetic Graphene Nanoribbon for Quantum Device) was scored as a high-quality project proposal in a highly competitive evaluation process (ranked in the top 15% of project proposals for the Marie Skłodowska-Curie Actions grant).

Publications selected for the journal cover: Angewandte Chemie, 2021, 60, 25224−25229; Chemical Communications, 2015, 51, 13162−13165; and – Journal of Materials Chemistry C, 2013, 1, 4536−4539.

During his scientific career, he had the opportunity to work in several academic institutions and to participate in various scientific projects. Between 2014 and 2016 he effectuated 2 postdoctoral stays in Barcelona at ICN2, and then at CIC nanoGUNE in San Sebastian, Spain. There, his work focused on the on-surface synthesis of graphene nanoribbons, characterized by low-temperature scanning tunneling microscopy. Between 2016 and 2020, he was a postdoctoral researcher at the Okinawan Institute of Science and Technology (OIST) in Japan, where his research focused on Perovskite material for solar cell application. His work requires the use of state-of-the-art Scanning Probe Microscopy and Photoemission Spectroscopies. After a brief comeback at CIC nanoGUNE for about a year, he moved to the University of Luxembourg, first as a postdoctoral researcher, and then as a research scientist. His work is now focused on improving the stability of Perovskite materials for photovoltaic applications.

Jeremy Hieulle obtained his Bachelor and Master in condensed matter Physics at the University of Strasbourg, in France. Then he pursued a PhD thesis at the Ecole Polytechnique, Université Paris-Saclay, in France.
