This work reported the properties of CdTe thin films which were grown onto CdS and CdS:O/CdS bilayer separately by using close-spaced sublimation (CSS). All the as-grown samples were characterized by XRD, FE-SEM, and UV-Vis-NIR spectroscopy, respectively. The XRD result showed that the interdiffusion was prompt for CdTe films deposited onto the CdS layer at source temperature 630 �C. In case of CdS:O/CdS bilayer, the interdiffusion was less pronounced. The SEM images exhibited very compact surface with grains in the range 2.2 - 2.3 �m and columnar growth morphology of the deposited CdTe films. The optical bandgap of CdTe grown on both layers were found to be around 1.46 eV. Finally, the influence of CdS1-x Tex intermixed layer on CdTe cells power conversion efficiency (PCE) was evaluated by the SCAPS-1D simulator. The incorporation of CdS1-x Tex intermixed layer enhanced the PCE of the simulated cell to 22.64%. � 2020 IEEE.
