The efficiency is around 4%, as in Figure 2 from the paper. SFE is solar-to-fuel efficiency.

From the paper, " We also calculated the solar-to-fuel conversion efficiency (SFE) for our photochemical process (Fig. 2C), obtaining a value of ~4.6% limited by the maximum efficiency of the PV-a-si-3jn cell (~6.0%) (13, 20). This SFE is higher than that of the water-splitting reaction (~2.5%) previously measured using an identical triple-junction photovoltaic (PV-a-si-3jn) cell (20). "

For comparison, most crop plants get 1-2% solar to biomass efficiency on the high end.
