QFLS values of perovskites with various carrier transport materials measured on the 1st, 2nd, and 3rd week of storage in a nitrogen-filled glovebox after fabrication. Samples “Ref” and “+ETM” (black), “RbI” and “+ETM” (red) were fabricated on quartz substrates with electron transport material (ETM). The “+ETM” denotes evaporatedC60on the reference (Ref) and RbI-containing perovskites surfaces. “+HTM” denotes the perovskite films fabricated on the ITO/PEDOT:PSS with PEDOT:PSS acting as HTM. “+HTM&ETM” denotes preparation on a glass/ITO/PEDOT:PSS HTM substrate with evaporatedC60ETM on the perovskite surface. The error bar of QFLS values is included.
