a J-V curves and corresponding PGD of a flexible double-sided SWCNT@85% device measured by double light source method. b Optical transmittances of SWCNT films and corresponding devices on glass and PEN, respectively. c Shelf storage (in dark) stabilities of all-carbon-electrode-based flexible PSCs and controls devices (both unencapsulated) at a temperature of 25 °C and a relative humidity of 55%. d Bending performances of flexible devices (bending radius of 4 mm, 1000 cycles) and the inset pictures show the graphs of a flexible control device (with orange border) and an all-carbon-electrode-based flexible device (with blue border).
