Near-infrared silicon solar cell response enhanced by gold nanoparticles with core-shell structure has been studied experimentally. The obvious enhancement on photocurrent response was observed when λ0 >; 800 nm and the highest value 12% near λ0 = 1160 nm was obtained.
The spontaneous emission (SE) rate enhancement due to surface plasmon polariton bandgap effect on copper grating was evaluated by calculating the dispersion relation and the electromagnetic field distribution simultaneously. Within the frequency range of silicon nanocrystals (Si-NC) luminescence ((h/2p)??=1.6 eV-1.9 eV), the calculated maximum averaged Purcell factors is about 30-163 for sinusoidal...
