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.
