Abstract Perovskites are of high potential in the ongoing academic research, due to their distinctive electrical properties and crystalline structures. Halide perovskites show light emissive panchromatic absorption across visible spectrum. The exceptional characteristics, such as long carrier lifespan, diffusion length, charge mobility, allow electric charges be transported collected effectively. Furthermore, by tuning cations anions composition, perovskite’s opto-electrical can altered. Moreover, dimension reduction affects band gap intrinsic features induce higher structural stability but at cost quantum confinement effect. Owing properties, halide being researched energy-related semiconducting applications, hold promise future looks bright. But challenges remain, larger question is what needs done make them more stable.
