Determination of the pure electronic diffusion properties. a Surface showing the best-fit between IPL(r,t) calculated with the diffusion-recombination model in Equation (3) and experimental data (black circles) acquired on a mixed halide perovskite thin film (ϕ0 = 5 × 106 photons per pulse). Fake colors indicate the PL intensity. b is a 2D map of the experimental data whereas c is a 2D map of the modeling results. d Logarithmic residuals map from the modeling. e–g Sensitivity analysis of the model to each parameter, displaying the IPL(r,t) for different values of τn (e) Dn (f) and Reh* (g) around the best fit parameters
