a, The current density–voltage scans of the PM6:D18:L8-BO IPV-anode at different light intensities measured in aqueous 1 M NaOH electrolyte at a 50 mV s−1 scan rate. b, The photocurrent density at +1.23 VRHE extracted from the current–voltage curves. c, The photovoltage of organic IPV-anode calculated from the onset potential shift under illumination by different light intensities compared with the dark current–voltage scan of the reference catalytic sheet. d, The current density–voltage scans of PM6:D18:L8-BO organic solar cells at different light intensities and a 40 mV s−1 scan rate. e,f, The light-intensity dependence of short-circuit current density (e) and open circuit voltage (f) of the organic solar cells. The open symbols represent the measured data points, while the solid lines show fitting by least squares regression.
