A total of 40 data points were measured between and 0.70 V in both the forward and the −0.1 reverse direction. For each type of devices, six cells were made and J-V analyses were done on them. Subsequently, the mean and standard deviation of JSC, VOC, FF and PCE of each device were reported in Table 1. Table S1.
