0101794卡特液体可加工固态半导体通过提供比传统加工半导体更低的能源，环境和加工成本的改进和新设备功能，显示出显着改变未来技术的承诺。在光电子应用的液体可加工材料中，聚合物基半导体提供了一些最高的电荷载流子重组和生成效率，并具有高度可调、灵活、重量轻和可掺杂的优点。尽管如此，制造高性能聚合物基器件仍然面临着巨大的挑战，因为在环境条件下，既难以实现高效的电荷注入，又难以实现高电流密度和长器件寿命。为了克服这些限制，最近对多层和混合聚合物结构的研究已经开始进行，这些结构包含电荷传输层。虽然这个方向很有前途，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、产生和重组？本提案的目的是通过多组分聚合物基发光二极管和光伏电池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。Sue Carter是加州大学的物理学教授，是聚合物光电器件的电学和光学特性方面的专家。J. Campbell Scott是IBM阿尔马登研究中心的研究人员，是有机发光器件设计、表征和仿真方面的专家。最后，国家可再生能源实验室的首席科学家大卫·金利（David Ginley）是光伏技术和无机半导体纳米粒子合成方面的专家。这种丰富的经验，加上他们对学生教育和这些领域发展的承诺，应该使他们能够实现他们的目标，对他们对多层聚合物光电器件的理解产生重大影响，增加他们在科学创新和技术可行性方面的潜力。

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.
