Fluence-dependent TRPL of MAPbI3 thin film at 77 K. (a) The excitation fluence dependent TRPL of the HE peak A. (b) The excitation fluence dependent TRPL of the LE peak B. (c and d) are color plots of the detailed fluence-dependent TRPL study of the HE and LE peak, respectively. The black dashed lines are the eye-guide for the evolution of the HE peak and LE peak TRPL maxima positions as the excitation fluence increases.
