Chemical deposition method, namely, modified chemical bath deposition (M-CBD) has been used to deposit copper iodide (p-CuI) thin films. The CuI thin films were deposited onto glass and FTO coated glass substrates from an aqueous medium at room temperature. To obtain good quality of thin films, preparative conditions such as concentration, pH of precursor solution and adsorption, reaction and rinsing time durations were optimized at room temperature. The structural, morphological, optical, electrical and photoelectrochemical (PEC) properties of the films were investigated. X-ray diffraction (XRD) patterns of p-CuI thin films reveals that the films have a zinc blende face centered cubic structure. The band gap was found to be 3.1 eV. The PEC studies showed that the material is a wide band gap.
