Morphological and elemental analysis of spray pyrolysis deposited CdS thin films for CdS/Cu2S solar cell heterostructure

Abstract: In this paper, room temperature deposition of CdS thin film on antimony doped tin oxide (ATO) substrate through spray pyrolysis technique. The size of thin film is estimated through field-emission scanning electron microscope (FESEM) FESEM and TEM (Quanta 200 and HITACHI SU8010) have been used to analyze surface morphology and particle size. The AFM(NT-MDT,INTEGRASpectra) was employed to analyze the topography and roughness of CdS thin film. The elemental analysis of the film was done by EDS spectra. The thickness of CdS film is also measured by AFM technique.
