Abstract

Disclosed is an opto-electronic device including a semiconducting substrate, a layered interface including at least one layer, the layered interface having a first surface in contact with a surface of the semiconducting substrate and the layered interface being adapted for passivating the surface of the semiconducting substrate, the layered interface having a second surface and the layered interface being adapted for electrically insulating the first surface from the second surface, and a textured surface structure including a plurality of nanowires and a transparent dielectric coating, the textured surface structure being in contact with the second surface of the layered interface, the plurality of nanowires protruding from the second surface and the plurality of nanowires being embedded between the second surface and the transparent dielectric coating.
