TRPL decay kinetics and b) steady-state PLQY measurement of neat perovskite films on glass with or without ETMs. In the TRPL measurements, a 405 nm pulsed laser with a fluence of 0.4 nJ cm-2per pulse and a repetition frequency of 1 MHz was used for excitation, and the decay kinetics were probed at the PL peak wavelength of 790 nm. In the PLQY measurements, 532 nm CW laser with 1-sun equivalent illumination intensity was used for excitation.
