Organic based device and method for manufacture thereof

A device comprising a first transparent and electrically conductive layer, a second electrically conductive layer, and a functional layer comprising at least one organic layer, sandwiched between said first and second conductive layers and to form a functional organic stack. At least one via is arranged to electrically interconnect said first layer and at least one segment of said second layer, the segment being electrically insulated from the reminder of the second layer. The present invention makes it possible to uniformly supply the first transparent layer with electrical power. The vias and segments are preferably formed by laser applied through the transparent conductive layer.
