a CD spectra of 2D chiral OIHPs obtained by using three different chiral molecules and then deposited on FTO. The molecular structures of the MBA, NEA, and BA 2D chiral OIHPs are illustrated in the inset images. b XRD spectra of 3D OIHP and the three different 2D chiral OIHP layers on 3D OIHP. c Cross-sectional SEM images of 2-NEA2PbBr4 (NEA 2D) on 3D (FAPbI3)0.95(MAPbBr3)0.05 deposited on an SnO2/FTO substrate. mCP-AFM analysis to determine the spin-dependent currents for (d) rac-NEA 2D chiral OIHP and (e) S-NEA 2D chiral OIHP coated on 3D OIHP. The error bars in the mCP-AFM analysis represent the current range of 30 samples, while the solid line data represent the average values.
