摘要：

Broadband light trapping is numerically demonstrated in ultra-thin solar cells composed of a flat amorphous silicon absorber layer deposited on a silver mirror. A one-dimensional silver array is used to enhance light absorption in the visible spectral range with low polarization and angle dependencies. In addition, the metallic nanowires play the role or transparent electrodes. We predict a short-circuit current density of 14.6 mA/cm(2) for a solar cell with a 90 nm-thick amorphous silicon absorber layer. (C) 2012 American Institute of Physics.
