Figure 4From: Axially connected nanowire core-shell p-n junctions: a composite structure for high-efficiency solar cells Current density with different diameters and current-voltage and power-voltage of the proposed structure. (a) The current density of the subcells as a function of diameters of shell NWs with a fixed D/P ratio of 0.5. (b) The current-voltage and (c) the power-voltage of the proposed axially connected NW core-shell p-n junctions with a NW diameter of 310 nm and D/P ratio of 0.5.Back to article page
