DESCRIPTION
Les nanomatériaux semi-conducteurs organiques offrent des solutions intelligentes et durables dans une large gamme d'applications dites "propres" : de la production d'énergie renouvelable à l'électronique. Le potentiel de marché pour les applications "nano-tech" organiques est donc énorme. Partant du constat que la majeure partie des nouvelles connaissances dans ce domaine se trouve aujourd’hui au sein des universités et des centres de recherches, le projet Organext a vu le jour afin de fournir une plateforme aux entreprises leur permettant d'utiliser les compétences développées par les partenaires du projet et de les diriger vers des applications et des produits innovants.
