【摘要】 聚对苯乙烯撑(PPV)由于具有优良的光电性质,是研究最多也是最有希望的光伏材料之一。然而单纯PPV作为光伏材料存在对太阳光利用率不高、载流子迁移率较低、稳定性不高等缺陷,制约了其实际应用。因此在围绕提高光伏效率和材料稳定性等基础上,近几年出现了大量PPV改性光伏材料。分析了新型PPV的各种改性措施的目的和相应的分子结构修饰方法,同时探讨了PPV光伏材料尚存在的问题和它作为高分子光电池材料的发展前景。更多还原

【Abstract】 Owing to good property of poly(para-phenylenevinylene) (PPV), PPV is one of the most hopeful photovoltaic materials.Although research on PPV photovoltaic materials is comprehensive, the property deficiency still exists in PPV.In this paper,the problems on PPV photovoltaic materials are discussed, and recent progress of how to solve the problems is presented. Some novel materials for improving PPV photovoltaic performance by structure design and modification are introduced. Some new issue and future prospects of PPV photovoltaic materials are also discussed in the paper.更多还原
