Commissariat à l'énergie atomique et aux énergies alternatives


CEA in short

CEA is the French Commission for Atomic and Alternative Energies; a public body with 16’000 people and EUR 4.3 billion annual budget. It is a technology research and development provider; whose role is to transfer its know-how to industry. Within CEA, the division LITEN is a major European research institute and a driving force behind the development of sustainable energy technologies of the future (renewable energies, energy efficiency/storage and development of materials). It includes the Department of Solar Technologies (CEA-INES), organized in Division spanning the entire PV value chain.

Main role and tasks in the project

CEA will lead WP9-JRA3, Characterization & standardization: stability, reliability, test protocols and standards. It will contribute in WP2-TA1, User friendly management of TA and VA to dedicated research infrastructures; WP3-VA1, Database infrastructure and simulation and data analysis tools; WP7-JRA1 Materials and device innovation infrastructure; and WP10-JRA4 Environmental, social and economic impact.

Key Persons involved in VIPERLAB project

Dr. Stéphane CROS
Dr. Stéphane CROSProject Manager

Dr. Eva Unger is a Young Investigator Group Leader at Helmholtz-Zentrum Berlin (Germany), affiliated with Humboldt University Berlin, and a Senior Lecturer at the Department of Chemistry at Lund University (Sweden). She received her Ph.D. degree from Uppsala University (Sweden) where she worked on Excitonic Dye Solar Cells. During her postdoctoral research at Stanford University (USA) she started working Perovskite Solar Cell devices as an early adaptor of the technology. Her current research focuses on scalable process development for the manufacturing of larger area Perovskite Solar Cells and the rationalization of material formation mechanisms from solutions to solid-state thin films. In VIPERLAB, her team supports an online perovskite solar cell device database "The Perovskite Database" for interactive data-queries, plots and any type of advanced analysis and AI-based projects.

Dr. Muriel MATHERONInfrastructure contact point

Muriel Matheron obtained her PhD in Material Science from the Ecole Polytechnique in 2005. She also graduated in 2001 from the Ecole Nationale Supérieure de Techniques Avancées (engineering school). She is currently Research Scientist at CEA, where she conducts research on silicon / perovskite solar cells fabrication and characterization. Over the past 8 years, her research has focused on the development of encapsulation systems and characterization tools to improve solar cells efficiency and stability (be it organic, perovskite and silicon / perovskite photovoltaics). She is co-author of over 20 papers in international scientific journals and holds 12 patents.

Dr. Matthieu MANCEAU
Dr. Matthieu MANCEAUInfrastructure contact point

He received his Master of Science in Chemistry from Clermont-Ferrand’s Superior National School of Chemistry in 2006. In 2009 he completed his PhD on the stability & degradation study of Organic Solar Cells at Blaise Pascal University (Clermont-Ferrand, France), in liaison with the Organic Photovoltaic group at CEA-INES. After a one-year postdoctoral stay at Risoe DTU in Denmark, he joined the Organic Photovoltaic group, CEA-INES, France in 2011 as a postdoctoral researcher and since 2012 as a research engineer for of organic & perovskite photovoltaic devices processing.

Dr. Adiren RIVALLANDInfrastructure contact point

Adrien Rivalland has a Ph.D. in Physics from the University of Nantes (2020). After a year as a junior lecturer at the University of Nantes, where he worked on Si/CIGS tandem solar cells, he joined the CEA-INES in 2021 as post-doc. He is working on the stability of Si/Perovskite tandem solar cells under electrical stress and illumination.


David Pelletier [M], PhD in Fluid Mechanics and Transfers, Polytechnic National Institute of Grenoble (France, 2006) and PhD in Chemical Engineering (Canada, 2006), he joined CEA where he is working as engineer/researcher on process development, scale-up at industrial level and industrial transfer of technologies. He worked at CEA during the last 14 years in charge of the topics related to Silicon purification, PV wastes recycling and circular economy where he gained a strong background in applied Physics & Materials Engineering. He is now closely involved into the development and the optimization of advanced cells technologies (PK, tandem) with a specific focus on numerical analysis.
