Optical Absorption Characteristic in Thin a-Si Film Embedded Between an Ultrathin Metal Grating and a Metal Reflector
We numerically investigated the effect of an optically ultrathin top metal grating in an absorber structure composed of an amorphous silicon (a-Si) thin film and a metal reflector for efficient solar cells. The ultrathin metal grating-based structure shows nearly polarization-insensitive net absorpt...
