  1. aThe devices were prepared under a humidity-controllable glove box. The dry air is under an RH < 10%.
  2. bThe humid air is under an RH ~50–60%.
  3. cThe integrated Jsc is shown in Supplementary Fig. 22.
  4. dAverage results are based on 16 devices for each condition.
  5. eThe ideality factors (nideal) are linear-fitted from the light intensity-dependent Voc graph in Supplementary Fig. 20.
  6. fThe minimum charge density (nmin) and build-in potential (Vbi) are calculated from the Mott-Schottky plot in Supplementary Fig. 21.
  7. gThe recombination lifetime measured under 500 nm LED illumination of 100 mW·cm−2, as illustrated in Supplementary Fig. 18.
