Comparative optimal energy conversion efficiency for AM 1.5 G solar illumination integrated over a 1 s timescale for a single junction (red shaded sphere) or tandem junction (blue shaded sphere) photoelectrochemical cell. The right panels provide example device architecture for a single junction (no change to overall optimum efficiency for multiple single junction devices mounted in parallel to the light source) and tandem DSPEC-DSSC water splitting cell
