Effect of morphology of ZnO nanowire arrays on photovoltaic and electron transport properties of DSSC

ZnO nanowire arrays were synthesized by hydrothermal method for 8, 10, and 12 hours. The array synthesized for 10h had the highest surface area and aspect ratio, and DSSC based on the 10h nanowire array revealed the best photovoltaic performance. The electron transport properties of DSSC based on the ZnO nanowire arrays were investigated by Electrochemical Impedance Spectroscopy (EIS).
