Light Absorption Enhancement in ThinFilm Solar Cells …

It is shown that whispering gallery modes in the spheres can be coupled into particular modes of the solar cell and signifi cantly enhance its effi ciency. We numerically demonstrate this enhancement using full-fi eld fi nite difference time-domain (FDTD) simulations of a nanosphere array above a typical thin-fi lm amorphous silicon (a-Si) solar cell structure.
