Title
(EN) PHOTOACTIVE NANOCOMPOSITE AND METHOD FOR THE PRODUCTION THEREOF
(FR) NANOCOMPOSITE PHOTOACTIF ET SON PROCEDE DE FABRICATION
Abstract
(EN)
The invention relates to a photoactive nanocomposite (3) comprising at least one pair of donor-acceptor semiconductor elements, wherein an element consists of a nanowires (7) doped with an sp3 structure and another element in embodied in the form of an organic compound (8). Said elements are carried by the substrate (1) of a device. A production method is also disclosed and consists, in a first embodiment, in picking, fonctionalising and solubilizing the grown nanowires in the organic element (8) and in depositing the mixture by coating on the device substrate. In the second embodiment, the nanowires (7) are formed on a growth substrate (5) which is embodied in the form of the device substrate. The organic element (8) is associated with the nanowires (7) in such a way that an active layer (3) is formed. The inventive photoactive nanocomposite makes it possible to produce a photovoltaic cell.

L'invention concerne un nanocomposite (3) photoactif comportant au moins un couple d'éléments semiconducteurs donneur-accepteur. L'un des éléments est formé de nanofils (7) dopés à structure sp3, et l'autre des éléments est un composé organique (8). Lesdits éléments sont supportés par un substrat (1 ) de dispositif. L'invention concerne aussi un procédé de fabrication. Selon un premier mode de réalisation, après leur croissance, les nanofils (7) sont prélevés, fonctionnalisés et sont solubilisés dans l'élément organique (8). Le mélange est déposé par enduction sur un substrat de dispositif. Selon un deuxième mode de réalisation, des nanofils (7) sont formés sur un substrat de croissance (5) qui est aussi le substrat de dispositif. L'élément organique (8) est associé aux nanofils (7) de façon à former une couche active (3). Un tel nanocomposite (3) photoactif permet la réalisation d'une cellule photovoltaïque.
