摘　　要：Highly efficient and stable polymer solar cells （PSCs） have been fabricated by adopting solution-derived hybrid poly（ethylene glycol）-titanium oxide （PEG-TiOx） nanocomposite films as a novel and universal cathode buffer layer （CBL）, which can greatly improve device performance by reducing interface energy barriers and enhancing charge extraction/collection. The performance of inverted PSCs with varied bulk-heterojunctions （BHJs） based on this hybrid nanocomposite CBL was found to be much better than those of control devices with a pure TiOx CBL or without a CBL. An excellent power conversion efficiency up to 9.05% under AM 1.5G irradiation （100 mW-cm^-2） was demonstrated, which represents a record high value for inverted PSCs with TiOx-based interface materials.高度有效、稳定的聚合物太阳能电池( PSC )被 poly 采用导出答案的混血儿制作了(乙烯乙二醇)钛氧化物( PEG-TiO <潜水艇class=“ a-plus-plus ”>一篇小说和通用阴极缓冲层( CBL )的 x </sub>) nanocomposite 电影，它罐头极大地由减少接口精力障碍并且提高费用抽取/收集改进设备性能。有改变的体积异质接面(BHJ ) 的转换 PSC 的性能基于这混合 nanocomposite CBL 被发现比有纯 TiO 的控制设备的那些好一些 < 潜水艇 class= “ a-plus-plus ” > x </sub> CBL 或没有 CBL。在 AM 1.5G 照耀下面的优秀力量变换效率直到 9.05%(100 mW 污獹獩 ? 潭敬畣慬? 楳癥? 慣慴祬楳?愠摮瀠潨潴慣慴祬楳？
