A high-performance fluorine-doped tin oxide(FTO) film was fabricated by flame-assisted spray deposition method. By varying the NH4F doping concentration, the optimal concentration was established as 8 at.%. X-ray diffractograms confirmed that the as-grown FTO film was tetragonal SnO2. In addition, the FTO film was comprised of nano-sized grains ranging from 40 to 50 nm. The heat-treated FTO film exhibited a sheet resistance of 21.8 Omega/ with an average transmittance of 81.9% in the visible region (lambda = 400-800 nm). The figures of merit shows that the prepared FTO film can be used for highly efficient dye-sensitized solar cells electrodes. (C) 2011 Elsevier B.V. All rights reserved.
