a Plots of current density change (ΔI) versus time. b Plots of d(ΔI)/dt versus time. a, b Visible and UV light are indicated by white and gray regions, respectively. c FFT analysis data from the plots in (b) (inset: magnified view of data at 0.25‒0.80 Hz). d Amplitudes and average amplitudes at the fundamental frequency peak f1 (5 mHz) and in the fundamental frequency band f2 (174 ± 25 mHz), respectively, and their harmonics obtained from (c).
