Figure 5From: Passivation ability of graphene oxide demonstrated by two-different-metal solar cellsCurrent versus voltage characteristics with AM 1.5 G illumination from the rear side. With rear illumination, ISC of the SiGb1, SiGb2, ConSi, and GbSi cells are 1.000, 0.999, 1.040, and 1.000 mA, and VOC are 0.400, 0.383, 0.374, and 0.370 V, respectively. GO samples own smaller JSC as compared to ConSi because partial input light will be absorbed by GO on the rear side.Back to article page
