Polycrystalline Cadmium Telluride (CdTe) thin films were prepared using thermal evaporation method at 150 °C substrate temperature. These samples were irradiated with 100 MeV (7+) oxygen ions for various fluences namely 1×1011, 5×1011, 1×1012 and 5×1012 ions/cm2, to study the irradiation effects on structural properties. X-ray diffraction patterns showed increase in crystallinity and enhanced microstructure up to the fluence of 5×1011 ions/cm2. For higher fluences 5×1012 ions/cm2, microstructure and surface morphology decreases which is an advantages as it increases the efficiency of the CdTe solar cells. The detailed studies have been presented and discussed in this paper.
