In this work, in order to effectively improve the electrical conductivity and visible light transmittance of ZnO thin films, ZnO single layer and ZnO/Ag bi-layer films were deposited on glass substrates by radio frequency and direct current magnetron sputtering, and then, the effects of an Ag buffer layer and electron beam irradiation on the electrical and optical properties of the films were investigated. The observed results indicate that ZnO 100 nm / Ag 7 nm films show higher opto-electrical performance than the ZnO single layer film. In addition, electron beam irradiation also effectively enhanced the visible transmittance and electrical conductivity of the ZnO/Ag bi-layer films.
