CdTe growth model by close spaced sublimation

Close spaced sublimation (CSS) has attractive features for high-rate deposition of CdS/CdTe thin film solar modules. It is necessary to have a solid growth model to explain their growth. In past 20 years, there are several growth models which are conflict each other. In this paper, a growth model was developed for CdTe deposition. The model can explain the effect of source and substrate temperature, ambient gas pressure and the separation between source and substrate on the growth rate of CdTe by CSS.
