In this research, three copper sulfide CuxS, x1.8-2 thin films with three copper-related precursors copper sulfate, copper chloride and copper acetate are prepared using spray pyrolysis method at 285oC on glass substrate and their physical properties are investigated. The FESEM images indicate the presence of nanostructures in the layers and XRD spectra show the formation of various structure, i.e. either polycrystalline and amorphous. In continue due to the special properties of samples transmittance and reflectance in sunlight controller application and filtering the unwanted and harmful wavelengths application, The effect of spray rates on the optical and electrical properties of one of this sample were studied.
