Journal ArticleDOI
Side Chain Engineering on Medium Bandgap Copolymers to Suppress Triplet Formation for High-Efficiency Polymer Solar Cells.
Lingwei Xue,Lingwei Xue,Yankang Yang,Jianqiu Xu,Jianqiu Xu,Chunfeng Zhang,Chunfeng Zhang,Haijun Bin,Zhi-Guo Zhang,Beibei Qiu,Xiaojun Li,Chenkai Sun,Liang Gao,Jia Yao,Xiaofeng Chen,YunXu Yang,Min Xiao,Min Xiao,Yongfang Li,Yongfang Li +19 more
TL;DR: It is demonstrated difluoro-substitution of thiophene conjugated side chain on donor polymer can suppress triplet formation for reducing carrier recombination and indicates that side chain engineering can provide a new solution to suppress carrier recombinations toward high efficiency.
Journal ArticleDOI

Shanshan Chen,Sungwoo Jung,Hye-Jin Cho,Na-Hyang Kim,Seungon Jung,Jianqiu Xu,Jiyeon Oh,Yongjoon Cho,Hyeongwon Kim,Byongkyu Lee,Yujin An,Chunfeng Zhang,Min Xiao,Hyungson Ki,Zhi-Guo Zhang,Ju-Young Kim,Yongfang Li,Hyesung Park,Changduk Yang +18 more
TL;DR: A strategy is demonstrated to simultaneously control the intercalation behavior and nanocrystallite size in the polymer-polymer blend by using a newly developed, high-viscosity polymeric additive, poly(dimethylsiloxane-co-methyl phenethylsil Oxane) (PDPS), into the TQ-F:N2200 all-PSC matrix.
Journal ArticleDOI
