Abstract

Article history: The Cadmium telluride (CdTe) thin film has been prepared by physical vapor deposition (PVD), the Ar + O Received 29 August 2015 pressure is about 0.9 kPa. This method is a newer technique to deposit CdTe thin film in large area, and Received in revised form 22 October 2015 the size of the film is 30 × 40 cm . This method is much different from the close-spaced sublimation Accepted 6 November 2015 (CSS), as the relevance between the source temperature and the substrate temperature is weak, and the Available online 12 November 2015 gas phase of CdTe is transferred to the substrate by Ar + O flow. Through this method, the compact and uniform CdTe film (30 × 40 cm ) has been achieved, and the performances of the CdTe thin film have Keywords: been determined by transmission spectrum, SEM and XRD. The film is observed to be compact with Large-area CdTe thin film a good crystallinity, the CdTe is polycrystalline with a cubic structure and a strongly preferred (1 1 1) CdS/CdTe solar cell orientation. Using the CdTe thin film (3 × 5 cm ) which is taken from the deposited large-area film, the Physical
