The Cu2S and SnS2 layers have been prepared by the chemical bath deposition method. The results of SEM and EDX analyses confirm a high stoichiometry of the synthesized semiconductor thin films. The optical properties of the Cu2S and SnS2 layers have been studied, and the optical band gap values have been determined.
