In this study, we observe that a dark mode is not necessarily prerequisite for an asymmetric Fano resonance to take place in plasmonic structures. The characteristic asymmetry feature of Fano resonance is retained in a plasmonic structure when both superradiant and subradiant oscillators are externally driven. Double Fano resonances are experimentally and theoretically observed where a common subradiant...
This study experimental demonstrated the plasmonic effects of Al-, In-, and Ag-nanoparticles (NPs) depositing on the silicon solar cells, respectively, according to external quantum efficiency and photovoltaic current-voltage. Efficiency enhancement of 22.68%, 20.88% and 17.10% for the cell with In-, Al- and Ag-NPs was obtained, compared to the reference cell.
Double Fano resonances are observed in a planar composite metamaterial possessing tripod plasmonic resonances, where a common subradiant driven oscillator is coupled with two superradiant oscillators. As a classical analogue of four-level tripod atomic system, the extinction spectrum of the composite metamaterial exhibits a coherent effect based on double Fano resonances. It is shown that a transfer...
We demonstrate experimentally the improvement of the external quantum efficiency (EQE) and current-matching of the triple-junction GaAs-based solar cell using periodic-patterns incorporated with random nano-sized indium-nanoparticles plasmonics. The average EQE decreased of −9.8% in top-cell and increased of +2.4% in middle-cell were obtained as the solar cell with periodic-patterns random nano-size...
We demonstrate the enhanced performances of Si-solar-cells using the spin-on-film device-processes and Indium-nanoparticle plasmonics. The short-circuit-current of the cell with indium-nanoparticles-plasmonics increase by 56.03% (from 3.48 to 5.43 mA) is obtained, compared to the bare-solar-cell.
