Huge Light Trapping with Surface Scattering Structures in a Flexible Transparent Substrate

We show in this study the fabrication of quasi-random and Gaussian random structures (2D random structures) with a photo-induced nanostructured material for the control of light-matter interactions. This material offers a novel approach for the design of richer Fourier spectra by using a pattern with different periodic structures and sub-structures that allow the control of the Fourier components at will. These structures can be used to achieve a huge efficient omni-directional light coupling in thin films and energy harvesting for solar cells.
