Journal ArticleDOI
Optimization of active layer morphology by small-molecule donor design enables over 15% efficiency in small-molecule organic solar cells
Cunbin An,Yunpeng Qin,Tao Zhang,Qianglong Lv,Jinzhao Qin,Shaoqing Zhang,Chang He,Harald Ade,Jianhui Hou +8 more
TL;DR: In this paper, the authors reported two small-molecule donors, namely, B3T-T, T and T-P, which differ only in their conjugated side chains: the former with a thienyl group and the latter with a phenyl unit.
Journal ArticleDOI
An inorganic molecule-induced electron transfer complex for highly efficient organic solar cells
Qian Kang,Yunfei Zu,Qing Liao,Zhong Zheng,Huifeng Yao,Shaoqing Zhang,Chang He,Bowei Xu,Jianhui Hou +8 more
TL;DR: In this article, a series of polynuclear metal-oxo clusters (PMCs) with gradually varied chemical compositions and photoelectronic properties were synthesized to enhance the power conversion efficiency (PCE) of organic solar cells.
Journal ArticleDOI
Optimizing polymer aggregation and blend morphology for boosting the photovoltaic performance of polymer solar cells via a random terpolymerization strategy
Tao Zhang,Cunbin An,Qianglong Lv,Jinzhao Qin,Yong Cui,Zhong Zheng,Bowei Xu,Shaoqing Zhang,Jianqi Zhang,Chang He,Jianhui Hou +10 more
TL;DR: In this paper, two random terpolymer donors (PBNB80 and PBNB50) were used to tune the molar ratio of electron-accepting units of 1,3-di(thiophen-2-yl)naphtho[2,3c]thiophene-4,9-dione (NTD), at the same time, the parent polymers were also compared to study.
Journal ArticleDOI
Red-emission organic light-emitting diodes based on solution-processable molecules with triphenylamine core and benzothiadiazole-thiophene arms
TL;DR: In this paper, a red-emission organic light-emitting diodes (OLEDs) based on solution-processable organic molecules with triphenylamine (TPA) as core and benzothiadiazole-(4-hexyl)thiophene (BT-4HT) as arms were reported.
Journal ArticleDOI
Effect of molecular spatial configuration on the photovoltaic properties of triphenylamine-containing D–A structured organic molecules
TL;DR: The photovoltaic properties of four triphenylamine (TPA)-containing organic molecules were studied by fabricating bulk-heterojunction organic solar cells (OSCs) with the organic molecules as the donor and [6,6]-phenyl-C71-butyric acid methyl ester (PC70BM) as the acceptor as mentioned in this paper.
