可控环境的有机柔性光电器件大面积制备与性能测试模块化集成设备系统

The process of organic thin-film photo-electronic devices is simple, low cost, and can be compatible with the flexible substrates, and the room temperature processing and a large area and mass production potential is expected to be widely used in various of applications. However, their instable properties for the organic devices and the lack of suitable processing techniques for preparation of larger area integration of organic photo-electronic devices make the feasibility of a vast of application problematic. Based on the instrument research project of the “Equipment system for an integration of multi-functional modules for preparation and characterization of larger-area organic optoelectronic devices under a controllable environment”, the key technical problems, we propose here a set of design principles of innovative technique solutions, such as the “roller” coating concept: by utilizing a flexible substrate sticking to the cylindrical roller which moves back and forth and meantime rotates along its axis to carry out the thin film deposition in a very large area. The “roller” deposition unit, the glove box and the low-temperature probe station can be combined together by using a transfer chamber unit to keep interconnection in a controllable environment equipment system. Our proposed concept equipment system may provide a novel experimental apparatus and integration techniques for the preparation of large area organic optoelectronics.
