Abstract

We developed revolutionary novel and low cost and nonvacuum chemical molecular beam deposition method for fabrication of thin film II-VI solar cells in the atmospheric pressure gas (He, Ar, H 2) 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 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. The effect of the composition and CdCl 2 treatment on the structure, intrinsic point defects, and electrical properties of CdTe films was investigated by XRD, AFM, Raman spectra, photoluminescence, and Hall methods.
