Preparation and Characterization of CdS by Evaporation and Cu2S Complex Photoelectric Thin Films

Cadmium sulfide (CdS) film by evaporation deposition and CdS/Cuprous sulfide (Cu2S) complex film by dipping were obtained on glass substrates. The influence of different annealing temperatures was investigated. Scanning electron microscopy (SEM) demonstrates CdS films are continuous, homogeneous. X-ray diffraction (XRD), photoluminescence (PL) and Raman spectra reveal the CdS films were hexagonal structure and 400°C is favor of the crystallization and aggregation. The conductivity of CdS/Cu2S complex film is better than that of CdS film.
