One-dimensional metal oxide nanorods show improved electrical and optical properties in the photoelectodes of dye-sensitizied solar cells (DSSCs). They can provide straight moving paths for electrons and reduced the electron hole recombination. In this study, ZnO nanoparticles and nanorods were synthesized by the spray-pyrolysis and thermal evaporation method. The effect of the ZnO nanostructure morphology on the photovoltaic preformance of a DSSC is investigated. The ZnO nanoparticle-based solar cell are 3.74 mA/cm2 and 0.771 V, while the ZnO nanorod-based solar cell has Jsc of 2.48 mA/cm2 and Voc of 0.751 V. This difference could be due to the difference in absorption behavior and surface area between the two types of ZnO nanostructures. At the IPCE data, the recombination of the nanoparticle/electrolyte interface occurs much lower than that at the nanorods/electrolyte interface.
