a J–V curves of the champion PSC devices based on reference, LC oligomer, and LCE. b J–V curves of PSCs measured in reverse and forward modes. c The efficiency distribution of 50 devices based on LCE. d Operational stability of the unencapsulated PSC devices based on reference, LC oligomers, and LCE in ambient air (40% RH). e Continuous operational stability of the unencapsulated PSC devices based on reference and LCE under flowing N2. GIWAXS patterns collected under vacuum during the operation of f the reference PSC and g LCE-based PSC for 0, 45 min, and 90 min. h Cross-sectional and bottom side-view SEM images of the corresponding PSCs collected after operational stability test. Scale bar: 1 μm.
