Abstract

ZnO nanorod (NR) structures have been fabricated using a precipitation method and applied as an effective scattering layer on the top of a ZnO nanoparticle (NP) electrode in a dye sensitized solar cell (DSC). This can effectively improve the light harvesting and enhance the photocurrent. Furthermore, the scattering layer decreases the charge recombination in DSCs, which is demonstrated by the results of the decreasing dark current and increasing recombination resistance. This leads to a remarkable 35% improvement in the conversion efficiency of the DSC using the ZnO nanorod scattering layer.
