Abstract

This study presented a plasmonic solar cell with AuNR arrays upon the active layer to enhance the conversion efficiency. AuNRs in 20 nm diameters with aspect ratio of 20 were assembled into an array by an AC electric field generated by micrometer spaced electrodes which called dielectrophoresis force. The AuNRs increase light scattering and trapping in the silicon layers leading to enhancement of the external quantum efficiency. Additionally, the short-circuit current with appropriate design of electrodes is increased from 20.45 mA to 33.09 mA and the conversion efficiency is increased from 4.22% to 7.01% under the applied 20 Vpp.
