organic solar cells, hybrid nanomaterials, printed electronics, inks
Mes travaux de recherche s’articulent autour de trois axes de recherches principaux. Le dénominateur commun de ces axes est l’interface hybride entre une nanoparticule (principalement de la famille des oxydes métalliques) avec un matériau organique. Les axes de recherche développés sont :
· Axe-A : le développement de nanomatériaux hybrides (organique-inorganique) de dimension et de morphologie contrôlées qui permettront de générer de nouvelles fonctionnalités par synergie avec des ligands organiques attachés à la surface des nanoparticules inorganiques,
· Axe-B : la réalisation et l’étude de cellules solaires hybrides ainsi que la compréhension des propriétés photovoltaïques des interfaces organique-inorganique semi-conductrices,
· Axe-C : la réalisation et l’étude de couches interfaciales dits « filtres électriques » dans des cellules solaires organiques.
