“…ZnO: Al (AZO) transparent conductive thin films get more and more attentions for their some advantages including low cost,high properties and non-toxicity , especially the high stability in hydrogen plasma during the fabrication process of silicon thin film solar cells by plasma-enhanced chemical vapor deposition [1][2]. Magnetron sputtering is the most widely used technology to prepare AZO thin films, which has characteristics of high deposition rate, low substrates temperature, good film adhesion, easy preparation for a large area etc [3][4][5].The improvement of the electrical and optical properties of AZO films is always a hot area of research.…”
