“…As shown in Figure 2b, the elemental ratio (at %) of the Cu/I is 1.06:1, which is near the standard stoichiometric composition [17]. Furthermore, other elements have also been found in the CuI thin films, including Al, Si, C, and O.…”

Copper iodide (CuI) thin films were grown on Si(100) substrates using a copper film iodination reaction method. It was found that γ-CuI films have a uniform and dense microstructure with (111)-orientation. Transmission spectra indicated that CuI thin films have an average transmittance of about 60% in the visible range and the optical band gap is 3.01 eV. By checking the effect of the thickness of the Cu films and annealing condition on the photoluminescence (PL) character of CuI films, the luminescence mechanisms of CuI have been comprehensively analyzed, and the origin of different PL emissions are proposed with Cu vacancy and iodine vacancy as defect levels.

This research focuses on the effect of thickness of CuI thin film for solid state dye sensitized solar cells application. Spin coating technique is done by varying the deposition layer that increases the film thickness. The 0.05 M of CuI solution is prepared at room temperature and deposited on the glass substrate. The electrical and optical properties were characterized by solar simulator and ultraviolet-visible -near infrared (UV-Vis-NIR) measurement respectively. The electrical characteristics indicate that the resistivity increases as the thickness increase due to difficulty of electron movement. Meanwhile, for the optical properties the films exhibited an optical transmittance of 86%-96% between 450nm to 800nm of wavelength.
