Organic, optoelectronic building element, process for the production of an organic, optoelectronic building element and process for material-coherent, electrical contact

摘要

Organic optoelectronic building element (100, 200, 300, 800), comprising:at least one contact pad (206, 208, 302, 304) with a first electrical contact area (526) and a second electrical contact area (524);The first electrical contact area (526) and the second electrical contact area (524) are electrically connected to the contact pad (206, 208, 302, 304);(i) where the first electrical contact area (526) and the second electrical contact area (524) are arranged side by side;where the second electrical contact area (524) has an adhesive layer (514, 516) which increases an adhesion between a material-soluble connecting agent (518, 520) and the layer on or above which the adhesive layer (514, 516) is formed; andThe contact pad (206, 208, 302, 304) is so designed that the first electrical contact area (526) is free of any material-like connecting agent.
