Ultralong Charge Carrier Recombination Time in Methylammonium Lead Halide Perovskites

Abstract: Due to their exceptional photovoltaic properties, metal halide perovskites (MHPs) are extensively studied for their potential applications in solar cells. In recent years, the power conversion efficiencies of MHPs-based solar cells rapidly increased from the initial few % towards more than 25 % for single-junction devices. Therefore, also taking into account their low costs and ease of manufacturing, MHPs-based solar cells have become the fastest-advancing photovoltaic technology. In this regard, much of th… Show more

“…For example, under the quasi-steady state assumption for n T (i.e., ), the rate equation for n is given as , where 1/ k 1 is the effective time constant of trap-assisted recombination process. Under the limiting cases of dominant trap-assisted recombination, the solutions are the well-known exponential decays (i.e., ). However, radiative recombination is not negligible in several cases.…”
