Understanding Transient Photoluminescence in Halide Perovskite Layer Stacks and Solar Cells

While transient photoluminescence (TPL) measurements are a very popular tool to monitor the charge‐carrier dynamics in the field of halide perovskite photovoltaics, interpretation of data obtained on multilayer samples is highly challenging due to the superposition of various effects that modulate the charge‐carrier concentration in the perovskite layer and thereby the measured photoluminescence (PL). These effects include bulk and interfacial...
