Influence of the growth and post deposition process on the properties of CdS thin films prepared by chemical bath deposition

Studies of the properties of CBD-CdS thin films grown under variable condit ions have been carried out. In particular, the influence of temperature, co ncentration of die reactants, application of a magnetic DC field and therma l annealing on the optical properties of the CDB-CdS has been studied. In t his work, we are focusing our interest in the influence of the combination of the last two conditions, i.e., magnetic field application and annealing at 65, 75 and 85 degreesC and a fixed c(thio)c(Cd2+) (ratio = 1) on die ban d gap energy of CBD-CdS thin films for its use in solar cell as window mate rial. The results about the influence of the substrate temperature and c(th io)/c(Cd2+) ratios in the final thickness of the layers is also presented.
