Performance of electricity generation. (a) Temperature curves of the top electrodes (upper) and the bottom electrodes (lower). (b, c) Open-circuit voltage (Voc) curves (b) and average Voc (c) of PPy-PCM, G-PCM, and G-blank versus time under illumination with Copt = 1 (white area) and after illumination (gray area). (d, e) Maximum current-voltage and power-voltage curves of PPy-PCM, G-PCM, and G-blank under illumination with Copt = 1 (d) and after illumination (e), respectively. (f) Average Voc of PPy-PCM under different optical concentrations.
