Abstract

We developed revolutionary novel and low cost and non-vacuum chemical molecular beam deposition method for fabrication of thin film II-VI solar cells in the atmospheric pressure gas (He, Ar and H2) flow. High quality polycrystalline CdTe films with different compositions (stoichiometric and Cd/Te ≤1.0 and Cd/Te >1.0) and thickness of 2-3 μm were fabricated on ceramic (SiO 2- Al 2O 3) substrates at a temperature of 600°C. Separate sources of Cd and Te with respective purities of 99.999% were used as precursors. The growth rate was varied in the range of 9- 30 Å s -1. The effects of the composition and CdCl 2 treatment on the structure, intrinsic point defects and electrical properties of CdTe films were investigated by X-ray diffraction, atomic force microscopy, Raman spectra, photoluminescence and Hall methods.
