Abstract

Nowadays, the efficiency improvement of the silicon solar cells (SCs) is a hot research topic in photovoltaic industry. Silicon nanowires (Si-NWs) offer a promising candidate for low-cost SCs with high-efficiency due to their unique optical and electrical properties. The Si-NWs can achieve highly efficient light trapping with reduced cost. In this paper, a novel design of asymmetric tapered nanocone Si-NWs is introduced and analyzed by 3D finite difference time domain (FDTD) method. The particle swarm optimization (PSO) technique is also used to optimize the geometrical parameters of the suggested design to maximize the optical efficiency of the suggested SC. The asymmetric Si-NWs offer an ultimate efficiency of 39.6 % with an improvement of 24 % relative to the conventional symmetric nanocone Si-NWs.
