Organic semiconductors are based on carbon compounds and allow an almost inexhaustible variety of materials. Devices based on organic semiconductors enable a variety of novel applications for flexible, lightweight, and environmentally friendly electronics. A first application success are OLED displays, which have already conquered a double-digit billion market and dominate the market in mobile phones.
In this talk, I introduce the material class of organic semiconductors and show with some examples from doping to organic solar cells the challenges of materials research and the implementation in products. Furthermore, vertical organic transistors with greatly improved properties are discussed, including bipolar transistors which open the GHz range for organic electronics. Finally, an outlook is given on a new form of neural networks based on organic semiconductors, allowing highly efficient neuromorphic computing approaches.
