Abstract	Hybrid density functional theory is used to study the formation energies and transition levels of point defects V-Cu, V-I, I-Cu, Cu-I and O-I in CuI. It is shown that the Heyd-Scuseria-Ernzerhof (HSE06) method can accurately describe the band gap of bulk CuI. As a solar cell material, we find that p-type semiconductor CuI can be obtained under the iodine-rich and copper-poor conditions. Our results are in good agreement with experiment and provide an excellent account for tuning the structural and electronic properties of CuI. Crown Copyright (c) 2012 Published by Elsevier B.V.
