In this research, CH3NH3PbX3 (X = Br, Cl) are synthesized and perovskite-based single-layer and perovskite-based bilayer diodes are fabricated. Using electron beam deposition technique, thin films of CH3NH3PbX3 (X = Br, Cl) hybrids with excellent homogeneity are manufactured. Absorption spectrum, X-ray spectrum and photoluminescence spectrum of organic/inorganic halide perovskites along with electroluminescence spectra, SEM micrographs and current–voltage characteristic of perovskite-based light-emitting diodes are investigated. Perovskite-based bilayer diodes are evaluated for the first time. The difference between the emission wavelengths of single-layer and bilayer diodes is the main characteristic of bilayer diodes.}, number={2}, journal={Journal of Theoretical and Applied Physics}, publisher={OICC Press}, year={2023}, month={Nov.}, keywords={Lead halide perovskite, Perovskite light, Thin Film, Electroluminescence, Emitting diode} }
