(Nantes Université, Laboratoire CEISAM)

Titre : Chemical approaches for sunlight conversion into electricity and fuels

Fabrice Odobel (1966) received his Ph.D. in 1994 at Strasbourg University under the supervision of Prof. Jean-Pierre Sauvage. After postdoctoral research with Prof. Ronald Breslow, Columbia University (New York), he joined CNRS as a full-time researcher in 1995. His research interests in CEISAM at Nantes University include the development of tailored molecular and hybrid materials for photovoltaic cells, artificial photosynthesis, and photodynamic therapy. A important aspect of the group activity is the dye chemistry and the synthesis of molecular systems for electronic and photonic properties.

Jacky Even (Plénière)

(INSA Rennes, Institut FOTON)

Titre : Halide perovskites: a new class of semiconductors for low-cost photovoltaics and optoelectronics

Jacky Even is a physicist, professor at INSA Rennes engineering school and senior member of IUF. He is heading the simulation activity of FOTON Institute (CNRS UMR 6082) since 1999. He had a broad scientific activity dedicated to fundamental material studies, both theoretical and experimental, and connection to the development of semiconductor nanostructures and optoelectronic devices for green energy applications, communication technologies, light emitters and quantum optical sources.
He is coordinating the research group in Rennes on halide perovskites since 2010, together with Claudine Katan from Rennes Institute of Chemical Sciences (ISCR, CNRS UMR 6626). These materials have achieved an unprecedented breakthrough in the history of photovoltaics in the last decade and now form a new class of semiconductors with many other low-cost optoelectronic applications related to thin films. The key for this topic is interdisciplinarity involving physicists, chemists and technologists.

Thèmes de Recherche : Perovskite, solar cell, optoelectronic, semiconductor

Hélène Brault is currently an Associate Professor in Chemistry at University of Nantes (Institut des Matériaux de Nantes Jean Rouxel, IMN-CNRS, Nantes, France). She obtained her Ph.D. degree in Inorganic Chemistry (2009) at University of Bordeaux (ICMCB, France), where she worked on opto-electronic properties of zinc oxide and fluoride. She obtained a Humbodlt fellow to join Martin Jansen’s group (Max-Planck Institute of Solid-State Chemistry, Stuttgart, Germany) in 2009 as postdoctoral researcher to investigate the role of high pressure on oxide containing lone-pair metals. Then, she joined the group of Dr. M. Mortier (LCMCP, Paris, France), to work on luminescent fluoride glasses. She became Associate Professor in Chemistry in 2011 at the University of Nantes, where she started working on various luminescent inorganic materials. Since 2016, her current research topics are mainly focused on lanthanide-based metal-organic frameworks for luminescence thermometry.

Thèmes de Recherche : Lanthanide, metal-organic frameworks, luminescence thermometry

The innovative company WAINVAM-E was founded in April 2020. The company designs and commercializes diamond-based quantum sensor solutions for various applications, including industrial control (non-destructive detection of corrosion and defects in metals), navigation (autonomous guidance of civil and/or military vehicles) and in vitro biomedical diagnostics (sensitive measurement of biomarker concentrations for screening and early diagnosis assistance). Based in Ploemeur (Morbihan), the company has 41 employees of various cultures and experience, 180 m^2 of R&D laboratories (physics, biology, chemistry), has filed 11 patents, and has won several innovation competitions to support its technological development (French Tech grant, iLab competition, BPI deep tech program).

WAINVAM-E's technological and commercial strategy is deliberately interdisciplinary and focused on the concrete applications of diamond sensor technology. WAINVAM-E is the only company in the world to design technological modules for all its applications, which feed each other. WAINVAM-E has already demonstrated the applicability of its solutions in non-destructive testing with industrial partners.

WAINVAM-E is part of the French Quantum Plan, in its "sensors and metrology" section. The company is perfectly in line with France's strategy, which was recently reinforced, to invest in Deeptech through the DeepNum20 programs. It is the only French startup and the largest company in the world in this specific field of diamond sensors.

WAINVAM-E offers a unique solution (made in France) to train university students and engineers at the Master level in quantum technology, with its WAINTEACH practical work in quantum physics.

The presentation will focus on the core of the technology (NV diamonds) at the heart of the different products and services proposed by WAINVAM-E, highlighting the need for interdisciplinarity and the culture of innovation required to develop such offers.

Thèmes de Recherche : Nitrogen Vacancy color center in diamond; quantum sensor ; magnetometry ; metrology; nondestructive testing ; in vitro diagnosis
