Cobalt doped tin oxide thin film (Co/SnO2) have been prepared by using spray pyrolysis method. The thin film were annealed at various temperatures ranging from 100 °C to 400 °C for one hour in a furnace. The effects of annealing temperature on the properties of thin film including structural morphology, electrical and optical properties have been characterized by the Field Emission Scanning Electron Microscope (FE-SEM), Energy Dispersive X-ray Spectrometry (EDS), Four point probe I - V measurement and Ultraviolet-spectroscopy (UV-Vis). Sample at 200 °C annealing temperature forming large grains shows the highest transmittance percentage that exceed 90% with 0.2k (Ohm-cm) of electrical resistivity.
