(a) Schematic illustration of MSNBsH in electrical simulation, (b) the current-voltage (I-V) simulation results, and (c) power density results of different structure-based devices under the illumination of AM1.5G solar spectrum. The blue curve is the typical I-V curve for structure with Au/SNBsH structure which has highest short-circuit density and power conversion efficiency. The pink curve is for structure with Ag/SNBsH structure which has highest short-circuit density and power conversion efficiency. The red curve is the SNBs structure with hemisphere Ag back reflector and the black one is the 1000 nm flat silicon structure with hemisphere Ag back reflector for comparison.
