Pb-Free Two-Dimensional Perovskite, Nanoparticulate, in the Solar Cells.

In this paper, the effect of combining (FTO/TiO2/Cs3Fe2Cl9/CuO/Al) in the energy conversion efficiency is studied. It creates a unique series with perovskite (Cs3Fe2Cl 9) serving as its primary source of visible light absorption. Using X-ray diffraction (XRD), a UV–Vis spectrophotometer, and scanning electron microscopy, the structural, optical and morphological features of the (CuO, Cs3Fe2Cl 9) nanoparticles were characterized (SEM). To create perovskite solar cells, these materials were effectively synthesized and deposited as thin films, and the efficiency of solar cells in photovoltaic (PV) devices has been verified. When the light intensity is 100 W/m2, the PV device's output demonstrates its energy conversion efficiency (PCE = 15.46%). [ABSTRACT FROM AUTHOR]
