CdTe thin films were grown on indium tin oxide glass substrates by a closed-space sublimation method using a resistor heater. Crystalline structure, morphology, and band gaps of the films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and optical absorption, respectively. The XRD analysis showed that the textures of the films were found to depend on the rate of increase in the heating current. The CdTe thin film had an (111) texture when the heating current rate was 2.0 A/min. The SEM analysis revealed that the film is composed of polyhedral grains of microns size. However, the (111) texture of the CdTe thin film observed by XRD decreased with the appearance of (220), (311), (400), (331), (422), and (511) peaks of the fcc CdTe phase when the heating current rate increased to 4.5 A/min. The (111) texture disappeared when the heating current was increased immediately from 0 A to the target current of 70 A. SEM results revealed that the grains in the film are round and the grain size is smaller than 1 μm. Optical absorption analysis showed that there is no distinctive difference in the band gaps of the films.

AbstractSolar cells (SCs) based on cadmium-telluride base layers, obtained by thermal evaporation and closed-space sublimation (CSS), are investigated. The base layers are activated via annealing in Freon. Structural and morphological studies are carried out to compare the recrystallization processes occurring during annealing in CdTе layers fabricated by different methods. The output parameters and light diode characteristics of the SCs are investigated, and the possibility of applying Freon annealing in the commercial production technology of thin-film CdS/CdTе SCs with base layers formed by thermal vacuum evaporation is analyzed.
