1. A transparent electrode, comprising:
a polymer matrix having semi-embedded therein a sintered silver nanowire composite comprising silver nanowires and metal oxide nanoparticles, wherein the metal oxide nanoparticles comprise n-type metal oxide nanoparticles selected from the group consisting of zinc oxide nanoparticles and titanium oxide nanoparticles,
wherein the silver nanowires and the metal oxide nanoparticles are sintered via ultraviolet ozone surface treatment after being wetted with a sodium borohydride solution to form the sintered silver nanowire composite, and
wherein there are no polyvinylpyrrolidone ligand on the surface of the transparent electrode.
