摘要：

Double-textured ZnO:Al (AZO) transparent conducting films were prepared successfully by a novel method, including the process of deposition, etching and re-deposition. Only one-step etching process was adopted during the whole procedure, and NaOH solution (5 wt%) was employed as the etchant. Double-textured AZO films exhibited higher haze values when the working pressures of deposition and re-deposition process were different. Effective improvement of light trapping was obtained from the double-textured AZO films prepared by this method. For the double-textured AZO films, the resistivity kept the order of 10(-3) Omega cm. The double-textured AZO films prepared by the novel method, which can be used as front electrodes, have potential application in thin film solar cells for light trapping. (C) 2015 Elsevier B.V.
