Thin films of the ternary material Cd1-xMgxTe were developed by the co-evaporation of CdTe and Mg at substrate
temperatures ranging from 300 to 400 °C. Films with band gap close to 1.6 eV were deposited on both corning glass as
well as CdS/Tec7 substrates depending on the end use. Films were characterized for structure, morphology, composition,
optical and optoelectronic properties. Similar to CdTe based solar cells, Cd1-xMgxTe/CdS devices also showed
dependence on the vapor chloride annealing temperature and Cu diffusion process. Stability of the material during
chloride annealing hampers high temperature annealing and recrystallization. With improved contact processing and post
deposition treatments we were able to fabricate Cd1-xMgxTe/CdS devices with efficiency over 7.5%.
