摘要

中文摘要 聚合物薄膜光伏电池作为一种潜在的新型可再生能源技术是目前国际上倍受关注的研究课题。聚合物薄膜光伏电池的能量转换效率与给体聚合物的光电性质和给受体共混薄膜相分离结构以及电极界面等密切相关,尤其给体聚合物材料的光吸收能力直接决定光伏电池短路电流的大小。该项目重点设计合成在可见光区宽吸收的新型三元共轭聚合物材料,并作为给体材料改善光伏电池在可见光范围内的光吸收能力。俄罗斯方面负责设计合成新型三元共轭聚合物,中方负责研究基于这种新型聚合物的共混薄膜凝聚态结构和光伏电池器件的制备和表征。双方将互派科研人员交流项目进展情况。期望该合作交流项目能够有效促进中俄双方在有机光电领域的科研人员的交流与合作,同时,期望取得的研究成果能够促进聚合物光伏电池研究的发展。
英文摘要 As a kind of promising renewable energy technology, polymer solar cells have drawn continuing research interest in the world. The power conversion efficiency of polymer solar cells are correlated with the optoelectronic property of polymer donor and the morphology of polymer donor/fullerene acceptor bulk heterojunction as well as the electrode interfaces. Especially, the absorption range of polymer donor plays an important role in determining the short-circuit current of the resultant polymer solar cells. The exchange program aims to design and synthesize new conjugated polymers with broad absorption in the visible range and use them as donors towards developing highly efficient polymer solar cells. Russia party is responsible for the design and synthesis of new conjugated terpolymers with broad absorption in the visible region and china party focuses on tuning the bulk heterojunction morphology and the fabrication of polymer solar cells based on these new polymer donors. Chinese scientists from Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, and russian scientists from A.N. Nesmeyanov Institute of Organoelement Compounds of Russian Academy of Sciences plan to visit each other to exchange the joint research progress. It is expected that this china-russia joint project would boost the exchange and cooperation between China and Russia community in the field of organic optoelectronics and the achievement may be favorable for the development of polymer solar cells.
