Figure 2

The IV characteristics of the triple-junction solar cell under (a) 1 sun and (b) 42 suns, which is the illumination concentration used for the 48 h electrolysis. The key performance parameters are included in the figure. IV curves were collected using both forward and backward voltage sweeps. These measurements generated identical results; thus, this figure shows only the forward sweep results.
