Aluminium doped Zinc Oxide (AZO) seed layers were deposited on Fluorine doped Tin Oxide (FTO) substrates using a spin coating technique. These were then immersed in growth solutions of zinc nitrate, hexamethylenetetramine and distilled water to develop nanoplates of Zinc Oxide (ZnO). The nanostructures of ZnO grown on FTO were studied using x-ray diffraction techniques. Dye-sensitized solar cells (DSSC) were fabricated using two prepared electrodes, one of dye-loaded zinc oxide and another that was platinum coated. The electrolyte used was potassium iodide iodine solution. The performance of the assembled DSCCs was tested by drawing an IV curve. The results showed that the short circuit current and open circuit voltages were about 10 microamperes and 270 millivolts respectively.BIBECHANA 13 (2016) 23-28

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.
