Synthesis and Characterization of Cspbibr₂ Thin Films Using Organic/ Inorganic Materials

ABSTRACT The development and examination of perovskite solar cells (PSCs) with organic–inorganic hybrid perovskite materials was undertaken in this study. Thin films of CsPbIBr₂ were prepared through spin-coating, which was followed by thermal annealing for different durations and temperatures in order to study the thin films' structures and optical properties. The films were examined through X-ray diffraction (XRD), scanning electron (SEM) and transmission electron microscopies (TEM), along with UV–Vis spectroscopy. The results showed enhanced crystallinity, optical transparency, and annealing. The results of this study support the use of CsPbIBr₂ in PSCs to convert solar energy to electricity, as well as emphasize the importance of variable controlled synthesis to improve device stability and efficiency.
