Research Progress in Conjugated Polymer Solar Cells Derived from Polycyclic Thienoacene

近年来,用于体异质结有机光伏器件的聚合物给体材料的发展受到了广泛关注,多环thienoacene与一些性能优良的电子受体单元构建的电子给体-受体型窄带隙共轭聚合物,具有良好的π-π堆积性能和高电荷迁移率,是当前高效聚合物太阳能电池的研究热点。本文概述了几类thienoacene基共轭聚合物作为电子给体与电子受体PCBM下的光伏器件的研究进展及取得的成就,同时对其存在问题与拟解决途径做了简要阐述。

The development of electron donor materials to be used for bulk heterojunction organic photovoItaic devices received much attention over recent years, and the electron donor - acceptor low bandgap conjugated polymers derived from polycyclic thienoacene and some useful electron acceptor moieties became the research hotspot for their good 7r - ~ o- verlap and high charge mobility. The research progress and achievements of photovohaic devices of poltcyclic thienoacene - based conjugated polymers as electron donor and PCBM as electron acceptor were summarized, followed with a brief ex- planation of its main existing problems and solve ways.
