Recently, lead iodide is the most materials employment in the perovskite solar cell
application. This paper has studied the character of preparation, structural and optical properties of
pbI2 materials. Structural properties are included investigation of the measurements X-Ray
Diffraction (XRD), Scan Electron Microscopy (SEM), Fourier Transform InfraRed spectroscopy
(FTIR) and Atomic Force Microscopy (AFM) tests to the PbI2 thin films samples. Optical
properties are included the investigation UV-Vis test of the thin film samples deposited on glass
substrates and investigated the Absorption, Transmittance and evaluated energy gap (Eg = 2.3 eV).
