Inorganics lead halide perovskite (LHP) have been became appropriate system for demonstrating light-matter interaction due to their flexible bandgap tunability, defect tolerance and high photoluminescence quantum yield nature. Although, LHPs have many hallmark properties which can support highly efficient photovoltaic devices, but they lost lot of energy in carriers-phonon scattering which slow down the recombination process and decrease the efficiency. Faster thermalization time of hot carriers support electron-hole recombination at band-edge which can be exploited in optoelectronic devices either by incorporating electrons/holes transport layer for photovoltaic or fast recombination for LED. Recently, efficient photovoltaic and light emitting devices are immediate requirement for high-speed quantum technologies.
