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.

通过“湿”工艺制造低成本制造的希望，例如喷墨印刷，刀片涂层和旋转涂层，在制造平板显示器，固态照明，太阳能电池和传感器中，长期以来一直是光电和光电电动机的有机半导体追求的主要动机之一。尽管在过去的二十年中取得了重大进展，例如，在展示市场中有机光设备（OLED）的统治地位越来越高，这些新产品中的绝大多数仍由常规（且昂贵的）“干燥”真空沉积方法制造。一个主要原因是，即使使用相同的材​​料，与真空沉积的对应物相比，湿式涂层工艺制造的设备的稳定性显着有限。较低的稳定性会随着时间的推移而迅速降低设备性能，从而使设备不适合大多数商业应用。拟议的研究旨在揭示这种现象背后的因素并开发控制它们的方法，从而使其生产有机光电和光伏设备，使用这些工艺的成本较低，因此使用这些工艺，因此廉价的产品，因此以较低的成本进行了较低的成本。该研究将利用适用的许多先进的实验技术，并将基于他以前在该领域的工作中的发现。六名研究生将参加这项研究。该研究结果对于将来开发耐用且廉价的有机发光设备和太阳能电池至关重要，这将与加拿大工业合作伙伴合作进行。因此，它将为这些合作伙伴提供竞争优势，这在下一代光电和能源收集设备方面具有巨大潜力。该研究还将允许培训新的加拿大研究人员的“品种”，这些研究人员将获得有可能启用新产品和市场机会的新兴技术专业知识。
