CAREER: Novel Triplet Polymer based Solar Cells as a New Path for Higher Efficiency

摘要该职业发展计划的研究目标是通过创造一系列新的三重态共轭聚合物来产生一种新型的高效有机太阳能电池，这些聚合物具有可控制的能级和从红外到可见光区域的带隙，这些都是目前无法获得的。目前的有机光伏（PV）主要基于单线态聚合物，激发态寿命短，吸收光谱窄，效率低(6 ？7%)。因此，迫切需要新材料来显著提高效率。使用长寿命三重态材料来提高器件效率是一个较少探索的领域。PI将解决这些独特的三重态聚合物及其在高性能有机太阳能电池中的应用的基本问题。具体的研究活动将包括新的三重态聚合物的计算和合成，对新的三重态聚合物的能量传输和生成过程的基本理解，以及高效三重态光伏电池的开发。通过提供一种完全不同的途径来解决当前基于单线态聚合物和器件的损耗和限制，所提出的工作将潜在地揭示阻碍高效聚合物太阳能电池发展的一些瓶颈。这个职业发展计划的教育目标是促进发现，同时促进各级教育的教与学。PI致力于将这一职业发展计划研究与教育推广计划结合起来，并让K-12、本科生和研究生，包括美国原住民和女性群体参与其中。南达科他州移动科学实验室将开发一个以教育为基础的聚合物光伏实验室站。移动科学实验室在学年期间前往全州各地的学校。移动科学实验室的主要目的是为南达科他州的学生提供一个使用先进设备、技术和方法进行科学实验室活动的机会，这些设备、技术和方法通常在小型学校是不可用的。未被充分代表的本科生和研究生印第安人和女学生将被鼓励和直接雇用到PI工作？s实验室。

CAREER: Novel Triplet Polymer based Solar Cells as a New Path for Higher EfficiencyAbstractThe research goal of this career development plan is to generate a new type of highly efficient organic solar cells by creating a family of novel triplet conjugate polymers, with controllable energy levels and bandgaps ranging from infrared to visible regions that are currently unavailable. The current organic photovoltaics (PV) are primarily based on singlet polymers with short-lifetime excited states and narrow absorption spectrum, and suffer low efficiencies (6 ? 7 %). Thus, new materials are strongly needed to significantly increase the efficiency. Using long-lifetime triplet materials to increase the device efficiency is a much less explored area. The PI will address the fundamental issues in these unique triplet polymers and their applications in high performance organic solar cells. The specific research activities will include calculation and synthesis of new triplet polymers, fundamental understanding of the energy transport and generation processes in the new triplet polymers, and development of highly efficient triplet PV cells. The proposed work will potentially reveal some of the bottlenecks which have hampered high-efficiency polymer solar cell development, by providing a completely different avenue to the losses and limitations in the current singlet based polymers and devices.The education goal of this career development plan is to advance discovery while promoting teaching and learning at all educational levels. The PI is committed to integrate this career development plan research with an educational outreach program and involve the participation of K-12, undergraduate and graduate students, including the Native American and female groups. An education-based polymer photovoltaic lab station will be developed for the South Dakota Mobile Science Lab. The Mobile Science Lab travels to schools around the state during the school year. The primary purpose of the Mobile Science Labs is to provide South Dakota students with an opportunity to perform science lab activities with advanced equipment, technology, and methods that are usually not available in small schools. Underrepresented undergraduate and graduate Native American and female students will be encouraged and directly hired to work in the PI?s laboratory.
