Well-arrayed zinc oxide nanorods applied as photoelectrodes for dye-sensitized solar cells were synthesized on an aluminum-doped zinc oxide substrate by the multi-annealing method. In order to improve the chemical stability and surface-to-volume ratio of photoanodes in dye-sensitized solar cells, the synthesized zinc oxide nanorods were coated with pure anatase phase titanium dioxide film using a novel mist chemical vapor deposition method. The effects of the titanium dioxide film on the morphological, structural, optical, and photovoltaic properties of zinc oxide–titanium dioxide core–shell nanorods were investigated. It was found that the diameter and surface-to-volume ratio of zinc oxide nanorods were significantly increased by coating them with titanium dioxide thin film. The power conversion efficiency of dye-sensitized solar cells was improved from 1.31% to 2.68% by coating titanium dioxide film onto the surface of zinc oxide nanorods.

Titanium dioxide (TiO2) nanoparticles have been recognized as a significant candidate for Dye SensitizedSolar Cell (DSSC) applications. A comparative study of the TiO2 films with two different patterns of the nanoparticlessize distribution is reported in this article. Crystallinity of the nanoparticles, distribution of size of nanoparticles and theperformance parameters of the DSSCs fabricated out of the films were thoroughly analyzed for the films of both types of TiO2.The TiO2 film with its nanoparticles distributed over a wider range showed better interconnection between the nanoparticlesand hence less porosity that resulted in lower area available for the adsorption of dye after sintering whereas the TiO2 filmwith its nanoparticles distributed over a narrower range showed relatively poor interconnection between the nanoparticlesleading to enhanced porosity suitable for DSSC application. A proper balance between porosity of the TiO2 film and theinterconnection between the nanoparticles can ensure the DSSC with improved performance parameters.The Himalayan Physics Vol. 4, No. 4, 2013 Page: 27-31 Uploaded date: 12/23/2013
