Fluorine doped tin oxide (FTO) films were fabricated on a glass substrate by a spray coating deposition methode. Non-toxic SnF2 was used as fluorine source to replace toxic HF or NH4F. Effect of SnF2 content, 0 – 10 mol% and 115 ppm graphene as comparison to the fluor content on the substrate, on structure, electrical resistivity, optical transmittance of the films and morfology were investig…
