摘要
We report a synergetic application of surface plasmon(SP) and field effect(FE) to improve crystalline Si solar cell performance. The SP are supported by small-sized Al nanoparticles with φ～15 nm. The localized SP electromagnetic field from Al nanoparticles excites electron-hole pairs at the surface of Si solar cell emitter, and meanwhile, the electron-hole pairs are detached by the electrostatic field that crosses the emitter surface, which leads to the production of extra charges and enhancement of Si solar cell efficiency. As compared to Si solar cell applying SP and FE independently, a more than 10% efficiency enhancement is achieved by using them synergistically.
