摘要:
In this work, single-nanowire solar cells (SCs) inlying configuration with a tunable rear metallic film are presented. Comparedto the standalone silicon nanowire (SiNW), a significant/broadband enhancementin the overall optical absorption of the SiNW with rear metallicnanoconfiguration was observed. The optimized fraction, corresponding to themaximal ultimate photocurrent, of the SiNW surrounded by metallic film wasachieved by properly engineering the SiNW radius and metallic film thickness.The considered configuration can be effectively extended to the alternativeconfiguration with a SiNW partially embedded in a metallic substrate, where theultimate photocurrent density of the 100 nm radius SiNW can be improved by75.50% relative to that of the freestanding SiNW. Our simulations verify thatit is a promising route for developing highly efficient single nanowire SCs.
