Abstract <p>The present work aims to prepare thin films of lead iodide (PbI₂) using the golden rain method. The optical, structural and electrical properties of these films were studied. The X-Ray diffraction (XRD) patterns showed that the structure of PbI₂ is polycrystalline and has a nanostructure with sizes up to 3 nm, which was calculated using the Williamson–Hall formula, while the scanning electron microscopy results showed that the PbI₂ structures have average sizes ranging from 72.2 to 111.8 nm. The optical properties results showed that the absorption peak was in the ultraviolet region at a wavelength of 290 nm. Finally, the electrical properties study using the Hall effect showed that the resulting material PbI₂ is a <i>p</i>-type semiconductor.</p>
