CA 2680025

The present invention uses lithographically patterned graphite stacks as the basic building elements of an efficient and economical photovoltaic cell. The basic design of the graphite-based photovoltaic cells includes a plurality of spatially separated graphite stacks, each comprising a plurality of vertically stacked, semiconducting graphene sheets (carbon nanoribbons) bridging electrically conductive contacts, and forming a Schottky contact with one of said electrically conductive contacts.

L'invention concerne l'utilisation d'empilements de graphite à motifs lithographiques comme éléments de construction de base d'une cellule photovoltaïque efficace et économique. La conception de base des cellules photovoltaïques à base de graphite comprend une pluralité d'empilements de graphite séparés dans l'espace, chaque empilement comprenant une pluralité de feuilles de graphène semiconductrices (nanorubans de carbone) empilées verticalement, pontant des contacts électriquement conducteurs.
