Preparation of non-fullerene acceptors with a multi-asymmetric configuration in a one-pot reaction for organic solar cells
TL;DR: In this article, two asymmetric non-fullerene acceptors (NFAs) 2FIFIC and ICIF2F were rationally designed by simultaneously introducing an asymmetric bridge and a terminal group into the A1-D-π-A2 configuration, and they were synthesized in a one-pot reaction and separated facilely using silica gel column chromatography.
Journal ArticleDOI
Enhanced efficiency in nonfullerene organic solar cells by tuning molecular order and domain characteristics
TL;DR: In this paper, the effect of 1-phenylnaphthalene (PN) additive in two high-efficiency polymer: nonfullerene blends (PTB7-Th:IEICS-4F and PM6:Y6) was investigated by combining X-ray scattering and calorimetric analysis.

High Voc solution-processed organic solar cells containing silicon phthalocyanine as a non-fullerene electron acceptor
Trevor M. Grant,Kayden L. C. Kaller,Trevor J. Coathup,Nicole A. Rice,Karin Hinzer,Benoît H. Lessard +5 more
TL;DR: In this paper, the authors investigated the use of bis(tri-n-butylsilyl oxide) SiPc ((3BS)2-SiPc) as a NFA paired with poly (3-hexylthiophene) (P3HT) and for the first time with poly [(2,6-(4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)-benzo [1,2-b:4,5-b’]dithiophene))-alt-(5
Journal ArticleDOI
The design of quinoxaline based unfused non-fullerene acceptors for high performance and stable organic solar cells
TL;DR: In this paper, the authors designed and synthesized two unfused non-fullerene acceptors with an electron-deficient quinoxaline (Qx) as the central unit linking with the electron-donating cyclopentadithiophene (CPDT) as conjugated backbone, which achieved a higher power conversion efficiency of 10.81% and better thermal and air stability than those of J52:UF-Qx-2F based devices.

TL;DR: In this paper, a ladder-type electron-deficient core-based central fused ring (Dithienothiophen[3.2-b]- pyrrolobenzothiadiazole) with a benzothiadiadiazoles (BT) core was proposed to fine-tune its absorption and electron affinity.
Journal ArticleDOI
An electron acceptor challenging fullerenes for efficient polymer solar cells.
TL;DR: A novel non-fullerene electron acceptor (ITIC) that overcomes some of the shortcomings of fullerene acceptors, for example, weak absorption in the visible spectral region and limited energy-level variability, is designed and synthesized.
