CdS and CdS:Li films were produced by means of ultrasonic spray pyrolysis (USP) method by spraying on glass substrates heated up to 340±5 ?C. LiCl in three different rates was added into the preliminary solution while producing the CdS:Li films. The effect of Li on the structural and optical characteristics of the CdS film was analyzed. XDR spectra showed that the crystallization degree decreases while lithium is 15% and increases when lithium rate increases. The crystallite sizes were calculated to be in the range of 60-85 nm. SEM photographs showed that the contribution of Li changed surface appearances of films and their particle size. All films exhibited the Raman peaks centered 298 and 590 cm-1 and the peak profiles were almost symmetric. The optical band gap and Urbach energy values of these films were determined. The maximum transmittance was found to be almost 80% for the visible region. LiCl which was added to the preliminary solution changed the optical characteristics of CdS film.
