The effect of Zn:Se ratio on the photoconducting properties of ZnSe thin films has been studied. The ZnSe thin films have been deposited onto glass substrates by the spray pyrolysis method, the substrate temperature kept at 430ºC using mixed aqueous solutions of ZnCl2 and SeO2 with different Zn:Se ratios. Their electrical, structural, and photoconductivity properties have been studied. The values of optical bandgap have been determined from the absorption spectra.
