We presented an application of nanometric layers of Cadmium Sulphide developed using Chemical Bath Deposition (CBD) technique for the growth of the CdS thin films. The thin films of CdS were synthesized employing two different complexing agent, acetilacetone and glycine. In this paper we compare the results of the thin films characterization with both complexing agent and the CdS thin film growth with glycine was selected in order to develop a Thin Film Transistor (TFT). The energy bandgaps in these cases were Eg = 2.53 eV using glycine as complexig agent, and Eg= 2.37eV using acetylacetone as complexing agent. An hexagonal polycrystalline structure concerning to the X-ray analysis results for both processes, from those studies were calculated their grain sizes by the model of Debye-Scherrer, resulting 3 nm for the acetylacetone process and 30 nm for the glycine process. Also we started with the computational analysis and preliminary results are presented.
