The deposition temperature of the bath in chemical-bath-deposited cadmium-sulfide thin films can directly affect the optical, electrical, structural as well as morphological properties of deposited thin films. The reporting work discusses the properties of chemical-bath-deposited cadmium-sulfide thin films deposited under steady chemical-bath temperature conditions at both 40 and 80oC and compares with films formed under variable bath-temperature conditions by varying the temperature of the chemical bath from 40 to 80oC and 80 to 40oC while depositing. The optical, electrical, structural, and morphological properties of the deposited films were examined by using ultraviolet-visible spectroscopy, photo-electrochemical cell, Mott-Schottky measurements, grazing incident X-ray diffractograms, scanning electron microscopy, and profilometry. According to the results, films deposited under steady chemical-bath temperature conditions show better optoelectronic properties compared to the rest, while films fabricated at 40oC are the best. Keywords: CBD, CdS, bath temperature, variable bath temperature, steady bath temperature.
