From: Fabrication-Method-Dependent Excited State Dynamics in CH3NH3PbI3 Perovskite Films

Normalised TA kinetics of MAPbI3 films fabricated by CHP, CBdrp, and IFF fabrication methods, probed at 760 nm with 400-nm excitation at the fluences of (a) 0.37 μJ cm−2, (b) 16.8 μJ cm−2, and (c) 58.8 μJ cm−2. Fits for the decays in (b) and (c) are shown in Fig. S4.
