On the understanding of energy loss and device fill factor trade-offs in non-fullerene organic solar cells with varied energy levels
Xuning Zhang,Xuning Zhang,Nannan Yao,Rui Wang,Yanxun Li,Dongyang Zhang,Guangbao Wu,Jiyu Zhou,Xing Li,Hong Zhang,Jianqi Zhang,Zhixiang Wei,Chunfeng Zhang,Huiqiong Zhou,Fengling Zhang,Yuan Zhang +15 more
TL;DR: In this paper, four groups of bulk heterojunctions (BHJs) NF-OSCs are investigated with FFs varying from 0.61 to 0.78 under progressive changes of HOMO-HOMO offsets (ΔHOMOs), and the results suggest that remaining appropriate energetic offsets is essential for controlling the carrier dynamics with longer-lived CS-states, restraining charge back transfer and reducing charge recombination toward high FFs and photovoltaic efficiencies.
Journal ArticleDOI
Fluorination-substitution effect on all-small-molecule organic solar cells
Qiong Wu,Qiong Wu,Dan Deng,Jianqi Zhang,Wenjun Zou,Yang Yang,Yang Yang,Zhen Wang,Zhen Wang,Huan Li,Huan Li,Ruimin Zhou,Ruimin Zhou,Kun Lu,Zhixiang Wei +14 more
TL;DR: In this paper, a benzodithiophene-based small molecule donor BDTF-CA with deep highest occupied molecular orbital (HOMO) energy level was designed for all-small-molecule organic solar cells (OSCs).
Journal ArticleDOI
Influence of Covalent and Noncovalent Backbone Rigidification Strategies on the Aggregation Structures of a Wide-Band-Gap Polymer for Photovoltaic Cells
Sunsun Li,Wenchao Zhao,Jianqi Zhang,Xiaoyu Liu,Zhong Zheng,Chang He,Bowei Xu,Zhixiang Wei,Jianhui Hou +8 more
TL;DR: In this paper, the Covalent and noncovalent (F···S conformational lock) was used to improve the backbone planarity and charge transport property of the wideband gap ester-modified polymer.
Journal ArticleDOI
Molecular dispersion enhances photovoltaic efficiency and thermal stability in quasi-bilayer organic solar cells
Xuning Zhang,Xuning Zhang,Yanxun Li,Dongyang Zhang,Guangbao Wu,Hong Zhang,Jiyu Zhou,Xing Li,Saud-uz Zafar,Jianqi Zhang,Zhixiang Wei,Huiqiong Zhou,Yuan Zhang +12 more
TL;DR: In this article, the authors proposed to improve the performance of PHJ-based OSCs through dilute dispersions of the PBDBT-2F donor into the acceptordominant phase with the sequential film deposition.
Journal ArticleDOI
Pushing the Efficiency of High Open‐Circuit Voltage Binary Organic Solar Cells by Vertical Morphology Tuning
TL;DR: In this article , a high open-circuit voltage (VOC) binary D18-Cl/L8-BO system was achieved by employing 1,4-diiodobenzene (DIB), a volatile solid additive.
