Journal ArticleDOI
Highly Efficient Ternary‐Blend Polymer Solar Cells Enabled by a Nonfullerene Acceptor and Two Polymer Donors with a Broad Composition Tolerance
Xiaopeng Xu,Zhaozhao Bi,Wei Ma,Zishuai Wang,Wallace C. H. Choy,Wenlin Wu,Guangjun Zhang,Ying Li,Qiang Peng +8 more
TL;DR: In this work, highly efficient ternary-blend organic solar cells (TB-OSCs) are reported based on a low-bandgap copolymer of PTB7-Th, a medium-band gap copolymers of PBDB-T, and a wide- bandgap small molecule of SFBRCN, which exhibit a broad composition tolerance with a high PCE over 10% throughout the whole blend ratios.
