Abstract

Metal halide perovskites are emerging as an intriguing class of solution-based semiconductors with significant potential for photovoltaics. In this study we investigate the triple halide perovskite (FA,Cs)Pb(I,Br,Cl)3, which is known to be amongst the most stable metal halide perovskite systems available. This stability allows a comprehensive study of the hot carrier dynamics to be assessed under steady-state conditions at high fluence and various temperatures in a device structure.Here, we show measurements support the presence of hot carriers in the device in advance of any negative effects due to halide segregation or decomposition.
