Effect of 100 MeV (7+) Oxygen ion irradiation on the structural properties of Cadmium Telluride thin films

PP: 37-41
Jayadev Pattar, Balakrishna K. M., Ganesh Sanjeev, Mahesh H.M.,
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 11011, 51011, 11012 and 51012 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 51011 ions/cm2. For higher fluences 51012 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.
