ZnO nanorod arrays have been synthesized on seed-coated indium tin oxide (ITO) substrates by a hydrothermal method from different thicknesses of seed layers. The ZnO nanorods obtained were investigated by scanning electron microscopy (SEM) to study the influence of different seed layer thicknesses on the orientation of the nanorods. The diameter of ZnO nanorods increased with increasing seed layer thickness. An X-ray diffractometer was used to verify the formation of ZnO nanorods on ITO. Well-aligned ZnO nanorods from various seed layer thicknesses were used as electron transporting layers in hybrid photovoltaic cells. Photovoltaic properties and power conversion efficiency (PCE) of devices made of ZnO nanorod arrays were investigated. PCE of up to 1.02% can be achieved from a cell made of ZnO nanorods grown on two suitable seed layers.
