Abstract
We propose an elliptical silicon nanohole (SiNH) array for broadband light absorption in thin film silicon solar cells. Our analysis shows that this architecture is capable of increasing the ultimate efficiency of a thin film silicon solar cell by 17.6 % in comparison to that of the circular SiNH array with the same fill fraction. Lattice symmetry breaking and extension of the irreducible Brillouin zone are responsible for the enhancement of the absorption.
