Tracked stability of the solar cell devices

(A) The stability of the unencapsulated control and MS-PSCs under ∼30% relative humidity.

(B) Long-term stability of the unencapsulated PSCs under continuous light irradiation in a N₂ atmosphere.

(C) The bending stability of FPSCs (R = 6 mm, ∼30% relative humidity, ∼25°C).

(D–I) Top-view SEM images of the perovskite film from FPSCs after 10 000 bending cycles at 6 mm, with the Au electrode removed by tape and spiro-OMeTAD removed by chlorobenzene.
