a, A schematic illustration of the inverted PSCs. b, I–V curves for the champion inverted PSCs based on SAM and SAB interface. c,d, IPCE spectra (c) and SPO (d) for PSCs based on SAM and SAB interfaces. e, Forward and reverse I–V scan results tested at the Shanghai Institute of Microsystem and Information Technology (SIMIT). f, I–V curves at 1 cm2 device active area for PSCs based on SAM and SAB interfaces. g–i, PCE evolution for the PSCs based on SAM and SAB interface under 1-sun MPPT following the ISOS-L-1 protocol (g), under dark conditions and 85 °C, 85% RH following the ISOS-D-3 protocol (h), and under dark, thermal cycling between −40 °C and 85 °C following the ISOS-T-3 protocol (i). Data in h and i are presented as mean values ± s.d. PCEs in h and i represent the average value from seven devices for each condition. The initial PCEs are noted in the inset of g, and initial average PCEs are stated in the insets of h and i. The error bars in h and i reflect the s.d. among seven devices.
