a Long-term moisture stability measurement of unencapsulated PSCs without and with SFX-P2 or SFX-P1 SAM modification, stored in ambient air with 30-40% humidity. b Thermal stability measurements of unencapsulated PSCs without and with SFX-P2 or SFX-P1 SAM modification at 85 °C in N2 atmosphere. TOF-SIMS elemental depth profiles of c fresh control PSCs and d fresh SFX-P1-modified PSCs. TOF-SIMS elemental depth profiles of e control PSCs and f SFX-P1-modified PSCs after 100 hours of aging in the air (30-40% humidity) at 85 °C. g Operational stability measurements of encapsulated PSCs without and with SFX-P1 SAM modification under one-sun illumination in ambient air (30–40% humidity) with MPP tracking. Inset: photographs of the encapsulated devices.
