electro-optical properties of cesium lead iodide: a computational approach.

Perovskite materials have garnered considerable attention in recent years due to their exceptional electrooptical properties, making them promising candidates for various applications in photovoltaics, light-emitting devices, and beyond. among these perovskite materials, cspbi3 stands out as a notable example due to its remarkable stability, tunable bandgap, and efficient light-emitting properties. the crystal structure, composition, and introductory properties of cspbi3 perovskite are being focused on using density functional theory (dft). in a detailed exploration of electronic, elastic, and optical properties, population analysis, and shedding light on the unique attributes of this material, this study highlights these attributes. to do the above computation, we have used castep in material studio.
