CATALYTIC TRANSPARENT ELECTRODE CONSISTING OF GRAPHENE FILM AND APPLICATION ON METAL NANOPARTICLES AND A METHOD FOR PREPARATION AND RESPECTIVE USAGES

摘要

This application describes a method for preparation and application of structured films of graphene platelets and metal particles, highly transparent and with catalytic and electrical conduction properties. In particular, the films mentioned above may be advantageously used as counter- electrodes in dye-sensitized solar cells, commonly called DSCs - "Dye-sensitized Solar Cells", as well as in other electrochemical or chemical devices, or in systems whose application also requires high electrical conductivity. Moreover, graphene is a material of great thermal, chemical and mechanical stability, and can therefore be used for applications in environments, and in more aggressive production processes.
