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

职业：本职业发展计划的研究目标是通过创建一个新的三重态共轭聚合物家族，产生一种新型的高效有机太阳能电池，具有可控的能级和带隙范围从红外到可见光区域，目前还没有。 目前的有机光催化剂主要是基于单重态聚合物，其激发态寿命短，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。 使用长寿命的三重态材料来提高器件效率是一个很少探索的领域。 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计算和合成新的三重态聚合物，对新的三重态聚合物中的能量传输和产生过程的基本理解，以及开发高效的三重态光伏电池。 这项工作可能会揭示一些阻碍高效聚合物太阳能电池发展的瓶颈，通过提供一个完全不同的途径来解决当前基于单重态的聚合物和器件的损失和局限性。这项职业发展计划的教育目标是在促进各级教育的教学和学习的同时推进发现。 PI致力于将这一职业发展计划研究与教育推广计划相结合，并涉及K-12，本科生和研究生的参与，包括美洲原住民和女性群体。 一个以教育为基础的聚合物光伏实验站将为南达科他州移动的科学实验室开发。移动的科学实验室在学年期间前往全州各地的学校。 移动的科学实验室的主要目的是为南达科他州的学生提供一个机会，用先进的设备，技术和方法来执行科学实验室的活动，通常是在小学校不可用。代表性不足的本科生和研究生美洲原住民和女学生将被鼓励和直接雇用在PI工作？的实验室。

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.
