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).

Solar energy is one of the main resources in our modern life. Photovoltaic panels are one of the most important technologies that make use of solar energy good because the photovoltaic cells harvest light from the sun and turn sunlight into electrical energy. This paper presents the manufacture of the solar cell from (Al/ZnO/perovskite/CuO/[Formula: see text]-Psi/Al) nanostructures using the drop-casting method at a 70∘C process temperature. Perovskite (Cs4CuSb2Cl[Formula: see text] nanostructures‘ structural, optical and morphological characteristics were identified by X-ray diffraction (XRD), SEM, UV–Vis spectrophotometer and AFM. This work generated a solar cell device with the highest energy conversion efficiency (12.49%) and filling factor of 33.7%, promising to create a high-quality polycrystalline crystal. In the current study, effective hybrid Pb-free Perovskite solar cells are explained and investigated.
