Characterization of PEC-PV tandem device.
(a) Schematic illustration of the PEC-PV tandem with the PV cell operating under reflected light from the photoanode. (b) I-V characteristics of the PV cell and the photoanode measured at standard (1 sun, 25 °C) and concentrated light (3 suns, 50 °C) conditions. (c) Utilization of the incident AM1.5G solar light by the tandem device calculated from the IPCE of the PEC-PV tandem sub-cells and the reflectance spectra of the photoanode. (d) Jp-t profiles measured for the PEC-PV tandem at 1 sun, 25 °C (blue) and 3 suns, 50 °C (red).
