Patent ID: 8808933

Claim:
A substrate; A tiled array of micron sized elongated semiconductor elements extending from the substrate and having a space between each elongated semiconductor element, wherein the semiconductor elements have diameters of at least 1 micron and an aspect ratio greater than 1; An infill material comprising polydimethylsiloxane located in the space between the elongated semiconductor elements; and A plurality of light scattering elements comprising voids, bubbles, dielectric particles, or metal particles included in the infill material and surrounding the elongated semiconductor elements, wherein the concentration of light scattering elements is higher in proximity to the elongated semiconductor elements, increasing the probability of absorption into the elongated semiconductor elements or wherein the infill material includes an infill bottom zone closed to the bottom of the structure than to an infill top zone, and the concentration of light scattering elements is higher in the infill bottom zone than in the infill top zone, the bottom of the structure being opposite to a zone exposed to incident light, such that light that is reflected or scattered upwards has more distance with which to interact with the wires; Wherein the array is tiled according to an ordered lattice pattern.
