中文摘要：
基于有机/高分子半导体材料的光伏技术在充分开发利用太阳能方面具有广阔的应用前景，受到广泛关注和研究。目前其实用化过程还面临诸多瓶颈，其中材料是影响能量转化的关键要素。本课题拟从材料的化学结构和空间结构设计入手，结合能级结构和带隙调控手段，探索实现有机光电转换材料功能化、高性能化和稳定化的有效途径。具体通过分子结构的多支化、多维化以及有效组装功能性基元（如低带隙基元、电子/空穴传输基元、给/受电子基元、p型/n型链段）等分子设计策略，制备一类结构明确、单分散性好、纯度高的新型多臂支化大分子光电转换材料体系，特别是多臂结构窄带隙电子给体材料、多臂结构电子受体材料和多臂结构"分子异质结"材料等；深入探讨材料化学结构、分子尺寸、空间维度与电子结构、能级结构和凝聚态结构以及光电转换性能之间的内在关联；设计开发出具有实用前景的高效光电转换材料及其太阳电池器件，为有机光伏技术的高性能化和实用化奠定基础。
