Abstract

The present paper concerns with the study of impact of merging (TiO2/Cs3Fe2Cl9/MgO) on FTO using the procedure of drop casting method at temperature (70°C). The structural, optical and morphological characteristics of the (MgO) nanoparticles were described via X-ray diffraction (XRD), UV-Vis Spectrophotometer, and scanning electron microscopy (SEM). The estimated value of the thin films (MgO, and Cs3Fe2Cl9) optical energy was (3.87) eV and (4.1) eV, correspondingly. The test results of the current–voltage elucidated that the ultimate power conversion efficiency (PCE) of solar cell was (7.57%), and factor of filling was (54.2). The present research elucidates and investigates the effective hybrid Lead-free Perovskite solar cells.
