Preparation and Properties of Al-Doped ZnO Thin Films for Solar Cells
Al-doped ZnO thin films were prepared by sol-gel process. Structural features and surface morphology were studied by XRD and AFM. The influence of Al-doped concentration and aging time to microstructure and electric resistivity were investigated. It was demonstrated that the best condition was Al/Zn ratios of 4.0at% and aging time of 48h.
