Transparent conducting coatings for solar cell application have been the subject of research over a number of years. The transparent conducting coatings were prepared by oven drying process on glass plates at various temperatures and various concentrations of the starting material stannous chloride (SnCl2.2H2O). Structural, morphological, optical, and electrical properties of the resulting plates were studied by XRD, Inverted Microscope, UV Visible and Hall Effect Measurement method. XRD showed a homogenous morphology of the coating. The minimum grain size of SnO2 was found to be 22 nm as calculated by XRD using Debye Scherrer Formula. The change in electrical conductivity and optical transmittance were found to be a function of the change in heating temperature, heating time and molar concentration of the starting materials. The coating prepared at 350°C for about 300 seconds with molar concentration 0.1M of the starting material showed low level of electrical resistivity (3.81E-02 Ω-cm) and high level of transmittance (transmittance maximum 79.2% at 600 nm ). The use of this transparent conducting electrode in a Dye Sensitized Solar Cell depicted the voltage of 315 mV and the resistance of 300 KΩ. All of the results indicate that the developed coating could be used in solar cell application.
