Fig. 2: PLQY maps of the samples under study plotted in the same scale for comparison.
From: Are Shockley-Read-Hall and ABC models valid for lead halide perovskites?

a Glass/MAPI, b glass/PMMA/MAPI, c glass/MAPI/PMMA, and d glass/PMMA/MAPI/PMMA. The horizontal grey lines show the values of PLQY (0.4, 0.2 and 0.02) in the single-pulse regime for the glass/MAPI sample (a) to set the benchmarks. Deviations from these values for other samples are shown by black arrows. The tilted grey line is the W0.5 dependence as predicted by the SRH model. It is shown to see better the difference in the quasi-CW regime from sample to sample. The pulse fluence (P1–P5) is indicated by the same colour code (shown in a) for all PLQY maps. Panel e shows the structure of the samples and geometry of the measurements.
