Figure 5From: Axially connected nanowire core-shell p-n junctions: a composite structure for high-efficiency solar cells Comparison of I-V characteristics and conversion efficiency with different D/P ratios. (a) The comparison of I-V characteristics between the proposed structure and the axial p-n junctions. (b) The conversion efficiency as a function of the D/P ratio. The numbers between every point are the efficiency, and NW diameter when current matching is achieved.Back to article page
