Impact of CdTe thin film thickness in ZnxCd1−xS/CdTe solar cell by RF sputtering
This paper presents the impact of thickness of RF sputtered CdTe thin film as an absorber layer through structural and optical characterization in ZnxCd1−xS/CdTe solar cells at lower concentration of zinc (Zn). The crystallographic, morphological and optical properties of CdTe thin film fabricated o...
