Biography

Nicolas Barreau holds a PhD in materials science from the University of Nantes (2001), and was awarded a “habilitation à diriger des recherches” in 2010. Following his PhD, he completed a post-doctoral contract (2002-2003) at the Hahn-Meitner Institute in Berlin. In 2005, he was appointed Maître de Conférences, section CNU63, at Nantes University, where he carried out his research in the Photovoltaic Materials Laboratory (LAMP, Dir. John Kessler). In 2008, he joined the Institut des Matériaux de Nantes Jean Rouxel (IMN, UMR6502). His research activities focus on photovoltaic conversion based on thin films of chalcogenide materials (eg. Cu(In,Ga)(Se,S)2) for applications ranging from tandem cells to photoelectro-catalytic conversion. He has (co-)authored over 200 papers (including proceedings) and seven patents.

CNRS Research Fellow

Senior Lecturer

Functions:

Lecturer and researcher

Qualifications:

Senior Lecturer HDR

Main research themes :

Synthesis of coordination polymers and MOFs based on lanthanides, luminescence thermometry

Biography:

Hélène Brault obtained her PhD in inorganic chemistry (2009) from the University of Bordeaux (ICMCB, France), where she worked on the optoelectronic properties of zinc oxide and fluoride. In 2009, HB was awarded a Humboldt Fellowship to join Martin Jansen’s group (Max-Planck Institute of Solid-State Chemistry, Stuttgart, Germany) as a postdoctoral researcher to study the role of high pressure on oxides containing lone-pair metals. HB then joined Dr. Michel Mortier’s group (LCMCP, Paris, France), working on luminescent fluoride glasses. Since 2011, HB has been a lecturer in chemistry at the University of Nantes, where she began working on various luminescent inorganic materials. Since 2016, her current research topics are mainly focused on lanthanide-based coordination polymers and MOFs for luminescence thermometry.
