Solution-processed organic thin-film transistors (OTFTs) have received enormous interest due to their great potential for realizing low-cost, lightweight and flexible electronics applications. Although several novel solution-processing techniques for achieving highly-crystalline organic semiconductor (OSC) films have been introduced to OTFTs, there still remains a challenging work to control thin-film properties. Here, I will present a new solution coating method that is compatible with a fast-moving roll-to-roll system by using a gap-controllable wire-bar and a bar-motion programming strategy. The developed method is highly practical and industry-friendly as well as feasible to fabricate high-quality OSC thin films in a large area at a high rate. A crystallization and growth mechanism of the bar-coated films and structure-charge-transport properties will be discussed. |
