This research discusses the effect of adding MEA additives on the synthesis of CuSnO3 thin films using the dipcoating method. This type of research uses experimental.. Based on UV-DRS analysis, the optimum bandgap data was obtained at 1.8034 eV. The addition of additives greatly influenced the reduction of the bandgap. With FPP, a good resistance of 38.59 Ω was obtained at 6x immersion, with a resistivity of 0.000330 Ωm with a conductivity value of 3030.30 Ω-1m-1. From the resulting data it can be concluded that the thicker the layer, the lower the resistance value, and the lower the resistivity, the better the electrical conductivity.
