Organic photovoltaic (OPV) technology has the potential of significant economic impact due to its unique features such as flexibility, low weight, and short energy payback time. In order to achieve greater commercial application, OPVs need to address significant technology challenges in large area device efficiency, stability, and benign/sustainable and safe production. This project will explore scalable, environmentally benign, sustainable and operator-safe ink-based processing methods to produce large scale OPV devices in ambient air conditions. The success of this project will contribute to the transformation of the Nation's energy infrastructure and help transition OPV technology to become a sustainable energy transformation technology that reduces fossil fuel use and reduces greenhouse gas emissions. The participating graduate and undergraduate researchers will benefit from the interdisciplinary nature of this project and will gain broad exposure to topics of material science, polymer chemistry, device physics and obtain marketable skills for careers in science and engineering. This work is embedded in the activities of the Organic and Carbon Electronics Laboratory (ORaCEL) at NCSU. Overall, the interdisciplinary nature of the research and its societal significance provides significant opportunities for educational outreach and curriculum development. The objective of this fundamental research project is to address organic photovoltaic technology needs for environmentally benign processes. This project will fabricate novel high efficiency semi-conducting polymer:non-fullerene based solar cells via blade-coating, a scalable fabrication technique. The OPV active layers will be processed with (a) petrochemical solvents such as anisole, o-methylanisole and THF that are safer and more benign than currently used chlorinated solvents, and (b) renewable, green biosolvents such as limonene, ethanol and potentially water. The molecular engineering needed will be guided by molecular interaction considerations and detailed structure-function-morphology relations. This project involves a multidisciplinary team comprising experts in synthesis (You), miscibility/thermodynamics (Ade), processing (Ade, You, Amassian), in-situ characterization (Amassian), and morphology characterization (Ade, Amassian). The overall strategy will be to provide feedback to the synthesis by validating molecular level guidance from Hansen solubility parameter calculations, miscibility measurements, and in-situ monitoring of morphology development. If successfully implemented, this work will improve process realization and economic feasibility and exceed current state-of-the-art.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

有机光伏（OPV）技术由于其独特的特征，例如灵活性，低体重和短的能源回报时间，具有重大的经济影响。为了实现更大的商业应用，OPV需要应对大面积设备效率，稳定性以及良性/可持续和安全生产的重大技术挑战。该项目将探索可扩展的，环境的，可持续和可驾驶的墨水处理方法，以在环境空气条件下生产大规模的OPV设备。该项目的成功将有助于国家能源基础设施的转型，并帮助过渡OPV技术成为一种可持续的能源转型技术，可减少化石燃料的使用并减少温室气体的排放。参与的毕业生和本科研究人员将从该项目的跨学科性质中受益，并将广泛接触材料科学，聚合物化学，设备物理学的主题，并为科学和工程领域的职业提供可销售的技能。这项工作嵌入了NCSU的有机和碳电子实验室（Oracel）的活动中。总体而言，研究的跨学科性质及其社会意义为教育外展和课程发展提供了重要的机会。该基本研究项目的目的是满足环境良性过程的有机光伏技术需求。该项目将通过叶片涂层（一种可扩展的制造技术）来制造新型的高效率半导体聚合物：非富烯太阳能电池。 OPV活性层将使用（a）（a）石化溶剂（例如苯甲酸盐，o-甲基烷酶和THF），它们比当前使用的氯化溶剂更安全，更良性，以及（b）可再生的，绿色的生物胶片，例如柠檬烯，乙醇，乙醇和潜在的水，以及潜在的水和潜在的水。所需的分子工程将以分子相互作用的考虑和详细的结构函数形态关系来指导。该项目涉及一个多学科团队，包括合成专家（您），可溶性/热力学（ADE），处理（ADE，您，Amassian），现场表征（Amassian）和形态学特征（ADE，AMASSIAN）。总体策略将是通过验证汉森溶解性参数计算，混溶性测量和形态发展的原位监测的分子水平指导来提供对合成的反馈。如果成功实施，这项工作将改善过程实现和经济可行性，并超过当前的最新最新。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准通过评估来获得支持的。
