Abstract At room temperature, ZnO/Cu/ZnO transparent conductive films were prepared on glass substrate by radio frequency magnetron sputtering of zinc oxide (ZnO) powder and copper (Cu) targets. The effect of the thickness of Cu layer on the photoelectric properties of ZnO/Cu/ZnO thin film were studied. The results showed that the surface of ZnO/Cu/ZnO films were relatively flat and had a good degree of crystallinity; in the visible light range, when the thicknesses of Cu are 11 nm and 14 nm, the achieved highest transmittance of ZnO/Cu/ZnO films were 79% and 74%; when the thickness of Cu is 14 nm, carrier concentration and the motion ability of charged particles are 4.85×1021 cm-3 and 6.73 cm2·V-1·s-1 respectively. Compared with ZnO/Ag/ZnO films, ZnO/Cu/ZnO required a thicker copper film to be continuous. ZnO/Ag/ZnO with a thinner Ag layer has better optoelectronic performance than ZnO/Cu/ZnO.
