Abstract
An optoelectronic device with an antireflective surface comprises a semiconductor substrate having a textured surface including a plurality of surface protrusions and/or indentations. A first electrode is in contact with the semiconductor substrate and spaced apart from a second electrode that is also in contact with the semiconductor substrate. The textured surface is fabricated by inverse metal-assisted chemical etching, and thus the semiconductor substrate is substantially devoid of ion-induced defects.
