Abstract

ZnO nanorod array films were deposited on seeded flourine-doped tin oxide substance with a chemical bath deposition method, and the dependence of the photovoltaic properties of the films on the annealing temperatures of seed layers was investigated. The energy conversion efficiency of ZnO nanorod-based DSSCs that contained seed layers annealed at 340°C was superior to that of DSSCs consisting of ZnO nanorods on seed layers annealed at 100°C. Electrochemical impedance spectroscopy revealed that the improved energy conversion efficiency is due to the enhancement in the electron transport within the seed layers.
