A strategy for improving the performance of organic electronic or optoelectronic devices that includes processing a conjugated polymer in the presence of a processing additive.
Existing polymeric systems for organic field-effect transistors suffer from high research and development costs as well as infrastructure tooling costs. The ability to improve their performance, without requiring the need to develop new polymers or optimize polymers, would greatly impact their utility.
Researchers at the University of California, Santa Barbara propose a strategy for improving the performance of organic electronic or optoelectronic devices that includes processing a conjugated polymer in the presence of a processing additive. Additives in a polymer system were found to significantly increase device operation. The field-effect mobility in the saturation regime is capable of improvement up to 2 times when compared to the devices processed from a single solvent. Further, studies demonstrated this effect on another polymer system, where the mobility was increased up to 6.7 times when compared to the control device. This system can improve performance without the need to develop or optimize polymers resulting in decreased research, development, and infrastructure tooling costs. The amount or type of processing additive and the type of conjugated polymer is adaptable and can be selected based on the desired enhancement of device performance.
