The Effect of Substrate Temperatures on CdS Film Prepared by Thermal Evaporation

Abstract

A suitable deposition method of CdS is necessary for the high performance CIGS(Cu(In0.7Ga0.3)Se2.2) solar cells. In this paper, CdS films were deposited onto glass substrates at the substrate temperture of 50°C、100°C、150°C by thermal evaporation, the effect of the temperature were presented. CdS film deposited at substrate temperture of 150°C was annealed at 150°C for 30min. All films were characterized for their morphology, structure and optical property using scanning electron microscope(SEM), X-ray diffractometer(XRD) and UV–VIS–IR transmittance respectively.The quantum efficiency of the fabricated solar cells with annealed CdS buffer layer was also enhanced at short wavelength. This new method leads to the improved performance of CIGS solar cells and also simplify the whole fabrication technology.

Deposition of Nanostructured CdS Thin Films by Thermal Evaporation Method: Effect of Substrate Temperature

“…The influence of temperature on the structural and functional properties of CdS thin films has been investigated in the recent past [ 23 , 24 , 25 ]. However, in previous studies on this topic, only a limited number of temperatures were selected, impairing the prediction of the best treatment temperature for suitably tuning the optical and electrical properties of thin films.…”
