Sébastien DUBOIS
Dr. Hab.
Fellow
Dr. Sébastien Dubois studied materials sciences at the National Institute for Applied Sciences (INSA) in Lyon and graduated with an engineering degree in 2004. In 2007 he received his Ph.D. in Physics from Marseille University.
After joining CEA-Liten in 2007, he conducted and supervised researches in the field of defect engineering, advanced characterizations, and homojunction solar cells.
He is currently responsible for the Alternative Cells Laboratory of CEA, with activities on silicon materials, high-temperature passivated contacts, heterojunction cells and tandem devices.
He is the member of the Scientific Committees of several international conferences and teaches the basics of silicon photovoltaics at the University of Nantes (France).
Research Activities The lab activity focuses first on the crystallization of monocrystalline silicon ingots and defect engineering strategies. In addition, a large part of our researches concerns high efficiency silicon-based solar cells with advanced passivated contacts (TOPCon, heterojunction) for single-junction and tandem devices. A particular attention is paid to the development of sustainable architectures and processes, minimizing for instance the use of critical materials. Our developments address both terrestrial and space applications.
