Figure 2: Open-circuit voltage versus short-circuit current. Short-circuit current is a proxy for how many excitons are being created, while open-circuit voltage is a proxy for how many of those excitons recombine, so we would expect that the relationship between the two would be different for a 635-nm excitation (mainly triplets) versus a 532-nm excitation (mainly singlets). We see no difference at room temperature.
