1. A method of fabricating a conductive metal nanowire network, the method comprising:
forming a transparent metal nanowire network comprising a plurality of metal nanowires and a plurality of junctions where metal nanowires meet;
immersing the network in a reaction solution;
illuminating the immersed network with light for a duration of time sufficient for selective growth of metal nanoparticles at at least a portion of the junctions;
removing the network from the reaction solution; and
drying the network.
