The structural advantages and localized surface plasmon resonance (LSPR) effect of Ag@SiO 2 nanowires when used as plasmonic antennas possess the features of fast electron transmission by 1D metal nanomaterials, high light harvesting, and electron–hole separation through the LSPR effect. By optimizing the concentration of Ag@SiO 2 nanowires (0.06 wt%) in the active layer of a device, high power conversion efficiency of 18.03% and a negligible photocurrent hysteresis are obtained.
