    Abstract:

    In this paper, n-type CdTe thin films were prepared by sputtering method. The morphology, structure and optical properties of n-type CdTe thin films deposited with different time and the influence of film thickness and annealing process on the photoelectrochemical (PEC) characteristics of n-type CdTe thin films were studied. The experimental results demonstrated that CdTe thin films with sputtering time of 25 min had better PEC performance. Annealing process could enhance the PEC properties of deposited n-type CdTe thin films. When CdTe thin films were coated with saturated CdCl2 solution and annealed in vacuum at 400 °C, the photocurrents of n-type CdTe thin films achieved 301 μA/cm2.
