11.4% Efficiency non-fullerene polymer solar cells with trialkylsilyl substituted 2D-conjugated polymer as donor.
Haijun Bin,Liang Gao,Zhi-Guo Zhang,Yankang Yang,Yindong Zhang,Chunfeng Zhang,Chunfeng Zhang,Shanshan Chen,Lingwei Xue,Changduk Yang,Min Xiao,Min Xiao,Yongfang Li,Yongfang Li +13 more
TL;DR: A trialkylsilyl substituted 2D-conjugated polymer with the highest occupied molecular orbital level down-shifted by Si–C bond interaction is developed and indicates that the alkylsilyl substitution is an effective way in designing high performance conjugated polymer photovoltaic materials.
Journal ArticleDOI

TL;DR: A novel small molecule acceptor MeIC with a methylated end-capping group is developed, which exhibits a higher lowest unoccupied molecular orbital (LUMO) level value, tighter molecular packing, better crystallites quality, and stronger absorption in the range of 520-740 nm.
Journal ArticleDOI
High‐Efficiency Nonfullerene Polymer Solar Cells with Medium Bandgap Polymer Donor and Narrow Bandgap Organic Semiconductor Acceptor
Liang Gao,Zhi-Guo Zhang,Haijun Bin,Lingwei Xue,Yankang Yang,Cheng Wang,Feng Liu,Thomas P. Russell,Yongfang Li,Yongfang Li +9 more
TL;DR: A nonfullerene polymer solar cell with a high efficiency of 9.26% is realized by using benzodithiophene-alt-fluorobenzotriazole copolymer J51 as a medium-band gap polymer donor and the low-bandgap organic semiconductor ITIC with high extinction coefficients as the acceptor.
