项目摘要

The last two decades have witnessed a strong interest in organic semiconductor-based optoelectronic devices for utilization in various applications including solid state lighting, flat panel displays and solar cells. This interest is motivated by a number of key advantages that organic semiconductors have, such as (i) the possibility to obtain light emission in a wide range of colors (ii) easier and cheaper fabrication including the ability to fabricate them on different substrates and in large areas, and (iii) their unique ability to realize mechanically flexible and transparent devices for next generation electronics. Despite their advantages, devices utilizing these materials, such as Organic Light Emitting Devices (OLEDs), Organic Solar Cells (OSCs) generally have lower durability in comparison to those based on traditional materials. We recently discovered that exposure to light, either from external sources, as in case of OSCs, or to light produced by the device itself, as in case of OLEDs, causes significant changes in these devices, especially at interfaces between different materials. This previously unknown phenomenon appears to be responsible for the fast deterioration in efficiency in these devices. The proposed research aims to uncover the factors behind this phenomenon and to develop approaches to control them, thus improve device service life. The research will utilize a number of experimental techniques pioneered by the applicant and will build on findings from his previous work in this area. Seven graduate students will participate in this research. The research results will be critical for future development of more stable OLEDs and OSCs, 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 electronics and energy conversion 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.
在过去的二十年中,在各种应用中,在包括固态照明,平板显示器和太阳能电池在内的各种应用中,对有机半导体的光电设备产生了浓厚的兴趣。这一兴趣是由有机半导体具有的许多关键优势所激发的,例如(i)以多种颜色获得光发射的可能性(ii)更容易且廉价的制造,包括能够在不同的基板和大面积上制造它们,以及(iii)它们独特的能力,可以实现机械灵活的和近乎跨越的设备以获得下一代电子电子功能。尽管具有优势,但使用这些材料的设备,例如有机光发射器件(OLED),有机太阳能电池(OSC)通常具有较低的耐用性,而基于传统材料的耐久性。我们最近发现,从外部来源(例如OSC)或设备本身产生的光(例如OLED)中,暴露于光线,尤其是在不同材料之间的接口上会引起重大变化。以前未知的现象似乎是这些设备效率快速定义的原因。 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,从而改善设备使用寿命。该研究将利用适用的许多实验技术,并将基于他以前在该领域的工作中的发现。七名研究生将参加这项研究。该研究结果对于将来的更稳定的OLED和OSC的开发至关重要,这将与加拿大工业伙伴合作进行。因此,它将为这些合作伙伴提供竞争优势,这在下一代电子和能源转换设备方面具有巨大潜力。这项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新兴技术的专业知识,该技术有可能启用新产品和市场机会。
