The team members.

The members of the group synthesize, characterise and test new organic materials in solar cells, and thermoelectric devices. Our research aims to understand the structure-properties relationships of these new materials, to implement them in devices, to improve their efficiency and to assess their robustness over time. 

The talented team

Dr. Cyril Aumaître
Permanent Researcher
Junior Scientist (CEA)

Cyril received his bachelor’s degree in chemistry from Bordeaux University (France) in 2011, and master’ s degree in polymer science from Grenoble Alpes University (UGA) in 2014. He obtained his Ph.D. in 2017 at UGA under the supervision of Dr. R. Demadrille and Dr. P. Reiss working on Dye-Sensitized Solar Cells.
He moved to Québec (Canada) for postdoctoral training with Prof. J-F. Morin and Prof. M. Leclerc at Université Laval on the synthesis of graphene nanoribbons for organic photovoltaic application. He recently joined the STEP laboratory as a permanent researcher in material chemistry. His main research interest focuses on the synthesis of new π-conjugated materials for energy production applications (bulk heterojunction solar cells, thermoelectricity, photocatalysis).

Samuel Fauvel
​PhD student

After a degree at the university of Avignon and graduating from university Grenoble Alpes, I joined the team as a PhD student under the supervision of R. Demadrille and C. Aumaitre. The aim of my thesis, within the ERC-PISCO project, is to develop dye-sensitized solar cells with variable optical transmission, and my work covers from the synthesis of the photochromic dyes to their integration in solar cells.

Yann Kervella
​Technician (CEA)

Yann received a bachelor's degree in chemistry and in physical chemistry from the university of Brest. After working for 5 years in a laboratory of the Grenoble Alpes University (UGA) on materials for OLEDs, he joined CEA in 2005.  He works now on the different projects developed in the team. He is specialized in the synthesis of pi-conjugated molecules and polymers. Yann is also the local contact in charge of the safety aspects in the STEP laboratory.​

Antonio Riquelme
​Post Doc

My name is Antonio Riquelme. I joined SyMMES (STEP) in September 2022 as a postdoc under the supervision of Dr. Renaud Demadrille in the framework of the ERC-Pisco project. I come from the warm south of Spain, where I did my Ph.D. at Universidad Pablo de Olavide, Sevilla, focusing on the ionic and electronic dynamics of new-generation photovoltaic materials. I needed a break from perovskites, so I moved here to study the optoelectronic properties of new photochromic dye-sensitized solar cells.​

Diego Mirani
​PhD student

I am Diego Mirani, I come from Italy where I got my bachelor’s and master’s degree in chemistry at University of Pavia. I joined STEP group in February 2022 for an internship period working on synthesis of additives for dye-sensitized solar cells. Now, since February 2023, I am a PhD student under the supervision of Dr. Renaud Demadrille with a project revolving around the synthesis of new photochromic dyes and their application in solar cells with variable and adaptable absorption.

Anthony Monmagnon 
​PhD Student

After a Master 2 "Polymers for Advanced Technologies" at University Grenoble Alpes. I started a PhD under the supervision of Dr. Sébastien Rolere at LITEN and Dr. Renaud Demadrille. The goal of my thesis is to develop new non-isocyanate polyurethanes (NIPU)

Claire Bourguignon
​PhD. Student

My name is Claire Bourguignon. In 2020, I obtained a Bachelor degree in Physics and Chemistry at the Sorbonne University and in 2022 I graduated with a Master’s degree in Inorganic Chemistry and Solid-state Physics at Paris-Saclay University. In 2022, I joined the SolHyCat team to work on the preparation and characterization of NiO photo-cathodes for applications in photo-electrocatalysis. I am now a PhD student under the supervision of Dr. M. Chavarot-Kerlidou and Dr. R. Demadrille to work on new robust and efficient molecular photocathodes for the production of solar fuels.
