Aqueous-processable conjugated materials and NIR-materials for organic electronics
Research Project , 2014 – 2017

Last years the development of organic electronics has been significant and, as an example, the best performances of polymer solar cells on a laboratory scale are now at the same level as amorphous silicon solar cells. It is envisaged that the devices will be manufactured on a large scale using printing methods resulting in low-cost electronics. This demands environmentally friendly deposition methods of the active materials without the use of harmful solvents. One aim with this project is to synthesize active materials that will allow the preparation of efficient polymer solar cells from aqueous solutions. This demands the development of both water compatible electron donor as well as acceptor materials. Another aim is to develop conjugated polymers that can emit and absorb light in the near infrared (NIR) region (750 - 2500 nm) that can be used to prepare different types of organic electronics. The novel devices would result in lower costs, and they could be used for example in the construction of large, flexible NIR-photodetectors. Materials for NIR emitting organic light-emitting diodes (OLEDs) with the potential applications in information processing and night-vision readable displays will also be developed. Additionally, materials for triple junction polymer solar cells with a sensitivity window extended into the NIR region will be developed allowing a better coverage of the solar emission spectrum and leading to an increased photovoltaic performance.
