Abstract
Close-spaced sublimation (CSS) of ultra-thin (similar to 3-4 mu m) CdTe layers for deposition on CdS-coated glass has been performed using a custom-designed CSS system. The deposition characteristics of CdTe have been studied on three types of CdS: firstly, CdS by Sputtering; secondly, CdS by CBD; and thirdly, CdS:O by Sputtering. Surface morphology was then studied using FESEM. XRD was performed to confirm the crystal properties of the film. UV-VIS spectrophotometery was used for determining the optical absorption and transmission characteristics of the film, which was further used to calculate the band gap of the deposited film.
