Copper (Cu) doped ZnO nanorod have been successfully grown on FTO surface using seed mediated hydrothermal method at 90°C for 8 hours. The grown copper doped ZnO material has been done using a precursor solution of 0.1 M Zinc Nitrate Hexahydrate (ZNH) and surfactant solution of 0.01 M Hexamethylenetetramine (HMT). The doping material was Copper (II) Nitrate Hydrate with various concentrations …
