a Sketch of the structure of the mesoscopic n-i-p PSCs based on Cs0.08 FA0.80MA0.12Pb(I0.88 Br0.12)3 perovskites and PTAA HTLs. b Schematic of the cell layout (active area = 1 cm2), in which the non-compact layers of the device are fully covered by the encapsulant. Two flat metallic ribbons are connected to the cell terminals to bring the electrical contacts externally. c Photograph of a representative mesoscopic PSC encapsulated with PIB:h-BN. d JV curves (reverse voltage scan) measured for a representative mesoscopic PSC before and after encapsulation with PIB:h-BN (before and after 240 h-ISOS-D1). e, f PV parameters of the mesoscopic PSCs without encapsulation and with PIB and PIB:h-BN encapsulants, acquired over >1000 h of ISOS-D-2 and ISOS-L-1 tests.
