Abstract

We report the fabrication and characterization of a facile and low-cost solution processed CuI/Si junction device for ultraviolet photodetector applications. The properties of CuI films are analyzed by Hall-effect measurement, X-ray diffraction pattern, ultraviolet–visible absorption spectrum, and field emission scanning electron microscope. The amount of iodine vacancies of CuI could be adjusted through subsequence anneals with/without iodine steam. Moderate process would improve the CuI crystallization and reduce iodine vacancies, and so thus raise the photocurrent and photo responsivity of CuI/Si junction. The made junction device performs a maximum Iphoto/Idark ratio of 3 × 104 to an ultraviolet light of 365 nm wavelength.
