Abstract
In an optical medium slab, a randomization of the interfaces will lead to an ergodic light propagation, implying a kind of light trapping that sets an upper limit for a broadband absorption enhancement factor. However, in thin film solar cells where such light trapping is most needed, it is not straightforward how the implementation of a surface randomization should be done. In addition, such randomization may also severely limit the electronic device performance. Here, a cylindrical periodic co...
