Title: Effect of molarity on properties of spray pyrolysed SnO{sub 2}:F thin films

Fluorine doped tin oxide (FTO) thin films were prepared by using automated Chemical Spray Pyrolysis (CSP) machine and the effect of concentration of the precursors on the conductivity and transmittance of the films were studied. The resistivity (ρ) and mobility (μ) are in the range of 10{sup −3}–10{sup −4} Ω-cm and 8.2–13.5 cm{sup 2}V{sup −1}s{sup −1} respectively. The electron density lies between 3.4 × 10{sup 20} and 6.6×10{sup 20} cm{sup −3}. The film transmittance varies between 70 to 80% and the films shows very good reflectivity in the IR-NIR region. Prepared films can be used as transparent electrodes in photo voltaic and optoelectronic devices.
