Abstract

Disclosed are conductive polymer solutions employed for the production of organic electronic components, which solutions are particularly useful for printing an organic element of an electronic component. To this end, particles of carbon black and graphite are used in the form of microplatelets in the polymer solutions. The components may include organic transistors and circuits, organic diodes, organic-based capacitors, organic photovoltaic cells, organic sensors and actuators, and combinations thereof.
