Measurement of Carrier Lifetime in Perovskite for Solar Cell Applications

Hybrid perovskite photovoltaics (PV) show promise because of their good efficiencies, which can be around 20%. Along with their PV characteristics, perovskite materials exhibit a high degree of radiative recombination. The kinetics of the photoluminescence decay can be employed to reveal important information concerning the optimization and characterization of perovskite photovoltaic materials. In this application note, the time-resolved emission from a perovskite photovoltaic is measured using the HORIBA DeltaFlex lifetime system.
