Abstract

A multi-laver device and its method of manufacture are disclosed. The multi-layer device comprises a first electrode layer, a first repair layer, a functional layer, and a second electrode layer. The first repair layer comprises a conductive hydrogel film or conductive hydrogel beads, the conductive hydrogel film or the conductive hydrogel beads comprising conductive filler particles dispersed in a cross-linked polymer. The repair layer protects the multi-layer device from electrical short circuits. A multilayer device is also disclosed including a light-transmissive electrode layer comprising a porous mesh or porous spheres.
