Abstract :
Enhanced absorption in silicon is needed to improve the efficiency of solar cells. Silver nanotoroids placed on top of a silicon substrate demonstrate larger absorption, will be presented. The method of moments is employed to compute the near electric fields absorbed in silicon substrate. The results show surface waves represented by large electric fields normal to the silicon surface and decayed as it gets deeper in the medium.
