The prospect of low cost, flexible and efficient organic electronic devices that can be easily printed like field-effect transistors, light-emitting diodes and organic or hybrid solar cells is highly attractive for various industries and their applications. However, producing such industrially relevant devices reliably requires a high control during fabrication as well as fundamental understanding of the physics of light absorption and charge transport properties of semi-crystalline, conjugated polymer systems and their donor-acceptor blends.
To systematically improve such devices a high degree of control during device fabrication is necessary. Otherwise improvement can only be achieved by trial and error. In our project CONTROL we propose to further develop a materials system where we have already shown a high degree of unprecedented control. Together with appropriate state of the art simulation and further co-developed modeling tools we will separately address different aspects of the devices one by one: recombination, exciton splitting and charge transport. Doing so we will gain fundamental progress in understanding charge transport processes which are extremely valuable for a large range of future organic electronics applications and material developments in general.
