Abstract

Optoelectronic device modules, arrays optoelectronic device modules and methods for fabricating optoelectronic device modules are disclosed. The device modules are made using a starting substrate having an insulator layer sandwiched between a bottom electrode made of a flexible bulk conductor and a conductive back plane. An active layer is disposed between the bottom electrode and a transparent conducting layer. One or more electrical contacts between the transparent conducting layer and the back plane are formed through the transparent conducting layer, the active layer, the flexible bulk conductor and the insulating layer. The electrical contacts are electrically isolated from the active layer, the bottom electrode and the insulating layer.
