Abstract

The morphology of ZnO films electrodeposited from zinc(II) nitrate solution depends on the reactant concentrations and the deposition current density. The relationship between the film morphology and suitability for application in dye-sensitized solar cells was evaluated, and it was observed that a leaves-type morphology obtained at low current density and high zinc(II) nitrate concentration gives the best performance, related to a high accessible surface area for dye adsorption.
