Physical Properties of Undoped and Doped ZnO Thin Films Prepared by Spray Pyrolysis for Photovoltaic Application


Al doped ZnO thin films were synthesized by ultrasonic spray pyrolysis technique. The concentration ratio of [Al]/[Zn] was varied from 1 to 5 %mol in the starting solution, in order to investigate the effect of doping ratio on the structural optical and electrical films properties. The films thicknesse was found in the range 900-1100 nm. X-ray diffraction… (More)
