Abstract

Textured optoelectronic devices and associated methods of manufacture are disclosed herein. In several embodiments, a method of manufacturing a solid state optoelectronic device can include forming a conductive transparent texturing material on a substrate. The method can further include forming a transparent conductive material on the texturing material. Upon heating the device, the texturing material causes the conductive material to grow a plurality of protuberances. The protuberances can improve current spreading and light extraction from the device.
