Multilayer Organic Semiconductor Devices by Blade Coating
|Keywords:||solution-process;blade coating;organic semiconductor|
Thin organic semiconductor film is usually deposited by spin coating in single layer because of the problem of mutual dissolution between the layers by the solvent. The single layer structure limits the flexibility of device design and the performance. In this project, based on new concepts and physics we will further explore the full potential of organic semiconductor in a new bade coating platform for general multilayer deposition developed in the recent years by us. Blade coating is the only method that prevents the mutual dissolution between different organic layers in solution-processed organic semiconductors. This method not only realizes the multilayer structure, but also significantly decreases the waste of organic material, and compatible with roll-to-roll fabrication. Furthermore, this method can be applied to a wide range of materials such as polymers, small molecules modified with side chains for solubility, and unmodified small molecules which is originally designed for vacuum evaporation. Blade coating method therefore combines the advantages of flexibility of multilayer design for small molecules and low cost solution process. In addition to the basic studies we will also gradually transform the academic research into a real mass production technology.
