In this collaborative project, four scientists at the University of California - Santa Barbara will investigate the design, synthesis and incorporation of new "electroactive polymer surfactant" (EPS) molecules in all-organic polymer photovoltaic materials. The aim of this research is to overcome some of the key stumbling blocks that have plagued other researchers investigating polymer photovoltaic materials, based upon bulk heterojunction systems. The work will be organized around the following three goals: (1) the development of physics-based models and efficient numerical methods for the prediction of phase separation in blends of rod-like polymers with multifunctional copolymer surfactants; (2) the synthesis of new homopolymers and functional block copolymers/oligomers comprising p-type and n-type backbones with a central electronically active moiety, using the design characteristics from (1); and (3) the characterization of the morphology of the blends as a function of composition and process conditions. The Principal Investigators will simultaneously develop a multifaceted educational program in solar energy research, including programs for high-school teachers, workshops for young scientists, and international collaborative experiences for graduate students. Efficient conversion of solar to electrical energy is likely to be one of the most important means of powering the planet in a sustainable way. Current materials for the conversion of sunlight to electricity are hampered by low efficiency and high cost. Work like that proposed in the present proposal seeks to find new alternatives that circumvent these problems. In particular, organic polymer (plastic) photovoltaic materials show promise as inexpensive alternatives to conventional semiconductor photovoltaic materials. Besides producing new kinds of materials for solar energy conversion, the Principal Investigators of this proposal hope to produce new kinds of scientists with the interdisciplinary expertise needed to make significant contributions to challenging scientific as well as societal problems.

在这个合作项目中，加利福尼亚大学的四名科学家将研究全有机聚合物光伏材料中新的“电活性聚合物表面活性剂”（EPS）分子的设计，合成和结合。 这项研究的目的是克服一些基于散装异质结系统的研究人员，困扰着其他研究人员进行聚合物光伏材料的关键绊脚石。 这项工作将围绕以下三个目标进行组织：（1）基于物理的模型的发展和有效的数值方法，用于预测与多功能共聚物表面活性剂的杆状聚合物混合物中相分离的相分离； （2）使用（1）中的设计特性，具有包含P型和N型骨架的新型均聚物和功能块共聚物/低聚物/低聚物的合成； （3）混合物形态的表征是组成和过程条件的函数。 首席研究人员将同时开发一项多方面的太阳能研究教育计划，包括针对高中教师的计划，年轻科学家的研讨会以及针对研究生的国际合作经验。太阳能向电能的有效转换可能是以可持续方式为地球供电的最重要手段之一。 低效率和高成本阻碍了将阳光转换为电力的当前材料。 像本提案中提出的那样的工作旨在找到解决这些问题的新替代方案。 特别是，有机聚合物（塑料）光伏材料表现出有望成为常规半导体光伏材料的廉价替代品。 除了生产用于太阳能转化的新型材料外，该提案的主要研究人员还希望生产出具有跨学科专业知识的新型科学家，以便为具有挑战性的科学和社会问题做出重大贡献。
