a J–V curves of the champion flexible PSCs based on LCE and reference, respectively. b J–V curves measured at different bending angles for reference and LCE-based flexible PSCs. c Normalized PCE values of flexible PSCs after bending 500 cycles with different bending radii. d Normalized average PCE values for flexible PSCs as a function of bending cycles with the bending radius of 4 mm. e Photographic image of the IoT system based on flexible PSCs under ambient light. The inset shows the wearable haptic device. f Time-dependent voltage for continuous tracking of the IoT system. The inset shows the light-on photovoltage. g Mechanical bending test for the integrated wearable device under continuous illumination. The inset shows the schematic illustrations of the integrated device under tension or compression strain.
