Cadmium telluride (CdTe) thin films were grown on fluorine-doped tin oxide glass substrate by electro-deposition technique at the temperature 75℃ in air ambient. The CdTe films have been grown for different times (1 h, 2 h, and 3 h), and their structural, optical, and morphological characterization was carried out through X-ray diffraction, high-resolution transmission electron microscopy, atomic force microscopy, UV–Vis spectrophotometry, and field emission scanning electron microscopy. The X-ray diffraction analysis revealed that the CdTe film was polycrystalline, with a cubic zinc-blende structure and a significant preferred (1 1 1) orientation. It was found that the deposition timings affected the surface morphology and average grain size of CdTe thin films, which were determined using field emission scanning electron microscopic images. Ease of deposition of P-type CdTe thin film with various morphologies at room temperature opens up new possibilities for heterojunction solar cell technology. Direct band-gap value for CdTe, estimated from absorption spectra and corresponding Tauc’s plots, ranges from 1.48 to 1.43 eV. The electrical characteristics of the CdTe layer significantly affect the efficiency of the prepared CdTe/CdS thin film, according to the J-V curve analysis and measurements of PV parameters.
