1. A method of forming a transparent electrically conductive film, the method comprising:
depositing a dispersion of metal nanowires onto a substrate surface;
delivering a solution comprising a fusing agent in a solvent onto the substrate surface; and
drying the substrate surface after depositing the metal nanowires and delivering the fusing agent solution to fuse the metal nanowires into a fused metal nanowire network, wherein the fused metal nanowire network has a transmittance for visible light at 550 nm through the fused metal nanowire network of at least about 85% and a sheet resistance of no more than about 250 Ohms/square and wherein the fusing agent comprises a metal halide salt.
