a Volume capacitance and area capacitance of a single CSMFE of the GE/CNFs@PANI ASSMFSC at different current densities. Schematic of the GE/CNFs@PANI ASSMFSC structure (inset). b Capacitance retentions of the GE/CNFs@PANI ASSMFSC with different bending angles at the current density of 0.5 mA cm⁻² (the inset: bending test experiment diagram). c CV curves of the GE/ CNFs@PANI ASSMFSC under different solar power densities, respectively.
