a Schematic diagram of the role of the MSN-SH layer in enhancing the stability of the buried interface. Top-view SEM images of the buried interface of perovskite films deposited on (b) ITO/PEDOT:PSS (control) and (c) ITO/PEDOT:PSS/MSN-SH (the MSN-SH sample) substrates. GIWAXS patterns collected on the exposed buried interface of (d) control and (e) MSN-SH perovskite films with an incidence angle of 0.1°. f FLIM measurements performed on the exposed buried interface of control, MSN, and MSN-SH perovskite films. g Stress-strain curve of the control, MSN, and MSN-SH perovskite device. (Inset) Experimental schematic for tensile stress measurement. h Residual strain analysis by linear fitting of 2θ-sin2ψ for control, MSN, and MSN-SH perovskite films. Source data are provided as a Source Data file.
