Abstract

In this study, novel design of semiconductor nano-wires in decagonal lattice with hybrid core is proposed and simulated using 3D finite difference time domain method. The hybrid core has gold/silicon combination to increase the light absorption and hence the ultimate efficiency. The reported NWs solar cell achieves broadband absorption in long wavelength region with excellent absorption (>95%) in short wavelength regime. The proposed structure with hybrid core shows an ultimate efficiency of 32.62 % which is higher than that of silicon core design by 19.7%.
