0101794CarterLiquid processable solid state semiconductors show promise of dramatically changing futuretechnologies by offering improved and new device functionality at significantly lower energy, environmental and processing costs than traditionally processed semiconductors. In the class of liquid processable materials for optoelectronic applications, polymer-based semiconductors offer some of the highest charge carrier recombination and generation efficiencies combined with advantages of being highly tunable, flexible, light weight and dopable. Nonetheless, significant challenges exist for making high performance polymer-base devices due to difficulties in achieving both efficient charge injection into the polymer and high current densities with long device lifetimes under ambient conditions. Recent work on multilayered and blended polymer-based structures that contain charge-transport layers has been undertaken to overcome these limitations. While this direction is promising, it has also introduced a new challenge, namely how do we understand charge injection, transport, generation and recombination in multilayered heterostructures of polymer-baseddevices?The objective of this proposal is to address this question through systematic experiments andsimulations on multicomponent polymer-based light emitting diodes and photovoltaics. Toaccomplish this objective, they have brought together an interdisciplinary team of three scientists from academic, industrial and government labs. Sue Carter, a physics professor at the University of California, is an expert in electrical and optical characterization of polymer-based optoelectronic devices. J. Campbell Scott, a Research Staff Member at IBM Almaden Research Center, is an expert in the design, characterization and simulation of organic-based light emitting devices. Finally, David Ginley, a principle scientist at the National Renewable Energy Laboratories, is an expert in photovoltaic technologies and the synthesis of inorganic semiconducting nanoparticles. This extensive experience, combined with their demonstrated commitment to the education of students and to the advancement of these fields, should enable them to achieve their goal to have significant impact on their understanding of multilayered polymer-based optoelectronic devices, increasing their potential for scientific innovation and technological viability.

CarterLiquid可加工固态半导体通过提供比传统加工半导体低得多的能源、环境和加工成本来提供改进的新设备功能，展示了极大地改变未来技术的前景。在用于光电子应用的液体可处理材料类别中，聚合物半导体提供了一些最高的电荷载流子复合和产生效率，并具有高度可调、灵活、重量轻和可掺杂的优点。然而，由于在环境条件下既难以实现高效的聚合物电荷注入，又难以实现高电流密度和长寿命的高电流密度，因此制造高性能聚合物基器件面临着巨大的挑战。最近关于含有电荷传输层的多层和混合聚合物结构的工作已经开始，以克服这些限制。尽管这一方向前景看好，但它也带来了一个新的挑战，即我们如何理解聚合物基器件多层异质结构中的电荷注入、输运、产生和复合？本提案的目的是通过对多组分聚合物基发光二极管和光伏器件的系统实验和模拟来解决这个问题。为了实现这一目标，他们召集了一个由来自学术、工业和政府实验室的三名科学家组成的跨学科团队。加州大学物理学教授苏·卡特是基于聚合物的光电子器件的电学和光学表征方面的专家。J·坎贝尔·斯科特是IBM Almaden研究中心的研究人员，是有机发光设备的设计、表征和模拟方面的专家。最后，美国国家可再生能源实验室首席科学家大卫·金利是光伏技术和无机半导体纳米颗粒合成方面的专家。这种丰富的经验，再加上他们对学生教育和这些领域的进步所表现出的承诺，应该能够使他们实现其目标，对他们对多层聚合物光电子器件的理解产生重大影响，增加他们的科学创新潜力和技术生存能力。
