“…10,11 Al-doped ZnO (AZO) films have got potential applications in solar cells, solid-state display devices, optical coatings, heaters, defrosters, chemical sensors, etc. 12,13 AZO is attractive for photovoltaic applications due to ZnO conductivity when doped with aluminium and transparency to the visible range of sunlight, i.e., minimized optical and electrical loss. 14 Several methods on the synthesis of various shaped ZnO nanostructured thin films are developed; for example, ZnO microrods were obtained by using spray pyrolysis, ZnO nanocomposite films deposited onto glass substrates were obtained by magnetron sputtering in different atmospheres, ZnO microrods were deposited by the hydrothermal method, ZnO nanofibres were deposited by electrospinning technique, and so on.…”
