A low-temperature controllable chemical bath deposition (CBD) method was demonstrated to prepare ZnO nanorod arrays. Our deposition technique includes the seeding and subsequent main CBD growth. The uniform growth ZnO nanorod arrays on the condensed ZnO seeding layer could be controlled by changing the processing parameters. Experiment results reveal that the ZnO nanorod arrays prepared under 0.03-0.05 M concentration with reaction temperature of 95 °C demonstrate the well-aligned orientation and optimum optical properties with high aspect ratio of ~21. The n-ZnO/p-NiO heterojunction electrode shows excellent rectifying behavior with extremely low leakage current. After the sensitization with N719, it is found that the degree of orientation and aspect ratio value play critical roles in the photovoltaic properties of solid-state dye-sensitized solar cells (SS-DSSCs).
