Abstract

A low temperature solution approach was employed to grow zinc oxide (ZnO) nanorods with various aspect ratios. Various sizes (diameter-10-25nm) of the nanorods were grown by changing the concentrations of the growth solution. The length (50nm-500nm) of nanorods was controlled using growth times. These one-dimensional (1D) nanostructures with direct paths for a charge transport with high surface area for light harvesting, are promising candidates for organic photovoltaics (OPV). The structural and optical properties of the prepared ZnO nanorods have been studied using SEM, XRD and UV-Vis absorption spectroscopy. Using as-grown ZnO inverted OPV was fabricated. ZnO nanorods were subjected to various doses of UV-ozone irradiation which led to improvement in transmission and hence enhanced device performance.
