The promise of low-cost fabrication via “wet” processes, such as inkjet printing, blade-coating and spin-coating, in manufacturing flat panel displays, solid state lighting, solar cells and sensors, has long been one of the main motivations behind the pursuit of organic semiconductors in optoelectronic and photovoltaic devices. Despite the significant progress in the last two decades, evident, for example, in the increasing dominance of organic light emitting devices (OLED) in the display market, the vast majority of these new products are still fabricated by conventional (and costly) “dry” vacuum-deposition methods. A primary reason is the significantly limited stability of devices made by wet-coating processes in comparison to their vacuum-deposited counterparts even when the same materials are utilized. The lower stability leads to a rapid decrease in device performance with time, rendering the devices unsuitable for most commercial applications. The proposed research aims to uncover the factors behind this phenomenon and to develop approaches to control them, thus make it produce organic optoelectronic and photovoltaic devices with long service life at a much lower cost using these processes, hence cheaper products. The research will utilize a number of advanced experimental techniques pioneered by the applicant and will build on findings from his previous work in this area. Six graduate students will participate in this research. The research results will be critical for future development of durable, yet cheaper, organic light emitting devices and solar cells, which will be pursued in collaboration with Canadian industrial partners. It will, therefore, provide those partners with a competitive edge in an emerging technology of tremendous potential for next generation optoelectronics and energy harvesting devices. The research will also allow training of a new “breed” of Canadian researchers who will acquire expertise in an emerging technology that has the potential to enable new products and market opportunities.

长期以来，通过“湿”工艺（例如喷墨打印，刀片涂层和旋转固态照明），太阳能电池和传感器来实现低成本制造的希望一直是追求光电子和有机半导体的动机之一。例如，在展示市场中有机照明设备（OLED）的统治时期，绝大多数新产品仍然是由湿wit制成的“干燥”真空启示方法的 - 与真空沉积事件事件相比，涂料的过程会导致设备性能随着时间的推移而迅速降低，从而使该设备不适合大多数商业应用。 拟议的研究旨在探讨tohinomenon的背后因素，并开发用于使用这些过程的有机源自和光电设备，并使用这些过程进行了许多高级实验技术。这项研究的研究结果对耐用的有机照明和太阳能电池的未来开发至关重要，这将与加拿大工业伙伴合作。设备。培训加拿大研究人员的新“品种”，他们将获得具有Oppor的产品的新兴技术专业知识。
