Claim Text:
1. A hybrid transparent conducting material (TCM) comprising: a polycrystalline graphene film comprising a plurality of grains having a bulk resistivity, the plurality of grains forming a plurality of low-resistance grain boundaries and a plurality of high-resistance grain boundaries, wherein the plurality of low-resistance grain boundaries each has a resistivity that is equal to the bulk resistivity and wherein the plurality of high-resistance grain boundaries each has a resistivity that is greater than the bulk resistivity; and a plurality of conductive nanostructures randomly dispersed in electrical coupling with the polycrystalline graphene film, the plurality of conductive nanostructures being positioned to span across the plurality of high-resistance grain boundaries to improve electrical conductivity across the plurality of high-resistance grain boundaries; wherein a density of the plurality of conductive nanostructures randomly dispersed in electrical coupling with the polycrystalline graphene film is below a percolation threshold.
