Ergodic Light Propagation in a Half-Cylinder Photonic Plate for Optimal Absorption in Perovskite Solar Cells

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 stra...
