ZnO nanoparticles (ZNPs) and ZnO nanowires (ZNWs) were fabricated via electrospinning and calcination. The ZNPs and ZNWs were blended with different mass ratio by varying ZNWs from 0% to 100% and serviced as photoanodic film of dye-sensitized solar cells (DSSCs) via spin coating. The efficiency of these DSSCs reached a maximum of 2.6% at 20 wt% ZNWs. In order to improve the photovoltaic properties of ZNWs/ZNPs hybrid photoanodic film, the ZNWs/ZNPs hybrid film was modified by the incorporation of multi-walled carbon nanotubes (MWCNTs) into ZnO matrix including both ZNPs and ZNWs combined with TiCl4 post-treatment. As a result, the efficiency of DSSCs increased from 2.6% to 3.8%, which is mainly attributed to the increased dye loading, faster electron transport, and less electron loss.
