中文摘要： 聚合物光伏电池具有廉价、无毒、可实现大面积柔性制备等显著优势。然而，较低的光电转换效率和较差的寿命及稳定性严重制约了其商业化进程。本项目从合成新型的给受体材料、光伏电池的界面修饰层、调控活性层的微观形貌等几方面开展研究工作以提高有机光伏电池的光电转换效率。对异质结微结构各功能材料之间形成的相态、尺度、能量传递、载流子迁移率等基本科学问题进行研究，获得相应的电池异质结微结构形态-效率之间的内在关系。相关研究结果在国际、国内SCI/EI刊物发表论文14篇。申报发明专利5项。电池的光电转化效率5%。培养研究生7名。获得省部级奖励2次。

英文摘要： Polymer solar cells are a promising alternative for clean, renewable sources of energy, and offer the combined attraction of light-weight, flexibility and low cost to manufacture by large-area roll-to-roll and free vacuum coating processes. The relative lower PCE of these photovoltaic devices is considered to be one of the major obstacles for the commercialization. There are many factors limiting the PCE of the organic BHJ solar cell and the poor charge transfer /transport is considered to be one of the main limiting factors. A key parameter for efficient charge transfer and transport is the three-dimensional nano-morphology of the active layer that provides a large interfacial area for excitons dissociation. This project investigated the effect of new donor-acceptor materials, buffer layer, thermal annealing and additive on the performance and morphology of polymer solar cells. Related research of this project have published 14 papers and applied 5 patents.The best optimized device exhibits enhanced performance ~5%. These research work enriched and developed the flexible OLED theory.
