abstract={Photoelectrochemical (PEC) solar cell studies of Al doped zinc oxide (AZO) thin film electrodes has been carried out by photocurrent-voltage (I-V) characteristic. The concentration of Al in ZnO was varied between 1-5 at.% in order to study the effect of the variation on the photovoltaic performance of the electrodes. The current-voltage (I-V) characteristics measured in the dark and under 80 W simulated illumination revealed enhanced PV performance for the AZO electrodes in contrast to the undoped electrode. The best response was achieved for AZO electrode with 2 at.% Al concentration thus, recording higher conversion efficiency and fill factor. This is a clear indication that AZO electrodes are superior to undoped ZnO in PV applications. The remarkable enhanced properties of Al doping on ZnO were carefully studied by means of thickness measurement, X-ray diffraction (XRD), scanning electron microscope (SEM) and UV-Vis spectroscopy, and the results were in good agreement, and confirmed that AZO thin film electrodes are better for PV applications than undoped ZnO semiconductor in sodium sulphate (Na<SUB>2</SUB>SO<SUB>4</SUB>) electrolyte.},
