INVESTIGATION OF MORPHOLOGY OF CdS THIN FILM PREPARED BY CHEMICAL BATH DEPOSITION METHOD

CdS thin films prepared by chemical bath deposition technique, are characterized using scan electron microscopy. In this observation our object to improve the understanding of the response of mechanisms associated with the formation of CdS thin films. CdS thin film behaves like an effective buffer material for film based poly crystalline solar cells (CdTe). Various type mechanisms are involved in the formation of CdS thin film, in which ion by ion mechanism has an important role in formation of thin film. In this formation glass slide is used as a substrate for deposition of CdS thin film. This work is done in ways, thin film was deposited at 70°C temperature glass substrate immersed into solution for 40 minutes and glass substrate immersed into solution at room temperature for 24 hours.
