In this research, we employed the finite-difference time-domain (FDTD) method to explore the impact of plasmonic aluminum nanoparticles (Al NPs) on solar cells (SC) consisting of hexagonal indium phosphide (InP) nanowires. The localized surface plasmon resonance (LSPR) observed in Al NPs contributes to a substantial enhancement in absorption near the band edge of InP. Our findings demonstrate that, for a low aspect ratio (D/P) of 0.3, optimizing the geometrical characteristics of the NPs leads to a 37.07 % increase in power conversion efficiency (PCE) for the suggested structure.
