Preliminary Study in Fabricating Fluorine-doped Tin Oxide by Using Spray Pyrolysis Methods

In this study, Fluorine-doped Tin Oxide (FTO) was fabricated by using spray pyrolysis methods for solar cells applications. The synthesis of FTO has been conducted under spray pyrolysis methods in which a precursor solution of SnCl2: F having a concentration of 0.1, 03, and 0.9 M. The spray pyrolysis was performed using a nebulizer with a deposition time of 2, 3, 5 and 10 minutes. The glass substrate was heated at a temperature of 400 degrees C prior to deposition. By Controlling concentration of SnCl2: F, FTO glass was successfully produced. The lowest sheet resistance of the FTO glass was about 60 Omega/cm(2). X-Ray Diffraction and Scanning Electron Microscopy were employed to investigate the characteristic of FTO. Then, FTO was applied as an electrode in the dye sensitized solar cell (DSSC) electrode application and the photovoltaic effect was observed.
