Voltammograms recorded at 50 mV s−1 in 0.5 M H2SO4 with chopped visible light for the same ITO\PEDOT:PSS\P3HT:PCBM\C60\MoS3 photocathode. Black: 1st cycle (same as Fig. 5); green: 2nd cycle; brown: 3rd cycle. Electrode area: 0.06 cm2. The oxidation current appearing at anodic potentials was also appearing in configurations without C60: thus, the oxidation current was not attributed to a possible reaction or degradation of C60 but more probably to the absence of equilibration time between the measurements.
