Abstract

• es via chemical bath deposition (CBD) method. SnO2 nanorods were prepared by immersing SnO2 seed layer coated FTO glasses into the aqueous solution. After fabrication process, the substrates were annealed at different temperatures and SnO2 nanorods were formed. And then, SnO2 nanorods were characterized by X-ray diffraction to observe crystal structure. Rods diameter and morphological properties at different temperatures were carried out from SEM analysis.SnO2 nanorods were obtained as an 1D structure. From this experiment, these nanorods would be used to construct the dye-sensitized solar cells (DSSCs) as photoelectrode. Current density –voltage (J-V) characteristics of DSSC with natural dye was measured. From J-V curve, conversion efficiency () and fill factor (FF) were evaluated for DSSC.
