Hybrid transparent conducting materials are disclosed which combine a polycrystalline film and conductive nanostructures, in which the polycrystalline film is 'percolation doped' with the conductive nanostructures. The polycrystalline film preferably is a single atomic layer thickness of polycrystalline graphene, and the conductive nanostructures preferably are silver nanowires.

Hybrid transparent conducting materials are disclosed with combine a polycrystalline film and conductive nanostructures, in which the polycrystalline film is 'percolation doped' with the conductive nanostructures. The polycrystalline film preferably is a single atomic layer thickness of polycrystalline graphene, and conductive nanostructures preferably are silver nanowires.

Illustrative embodiments of hybrid transparent conducting materials and applications thereof are disclosed. In one illustrative embodiment, a hybrid transparent conducting material may include a polycrystalline film and a plurality of conductive nanostructures randomly dispersed in the polycrystalline film. In another illustrative embodiment, a photovoltaic cell may include a transparent electrode comprising polycrystalline graphene that is percolation doped with metallic nanowires, where the metallic nanowires do not form a percolation network for charge carriers across the transparent electrode.
