Journal ArticleDOI
Blade-Cast Nonfullerene Organic Solar Cells in Air with Excellent Morphology, Efficiency, and Stability.
TL;DR: It is demonstrated that blade-coating can induce a higher degree of molecular packing for both conjugated polymer donors and small-molecular acceptors as it helps to produce a seeding film containing numerous crystal grains, subsequently providing nucleation sites for the residual solution when the motion of the blade exposes a liquid front.
Journal ArticleDOI
Two compatible nonfullerene acceptors with similar structures as alloy for efficient ternary polymer solar cells
Wenyan Su,Qunping Fan,Xia Guo,Xiangyi Meng,Zhaozhao Bi,Wei Ma,Maojie Zhang,Yongfang Li,Yongfang Li +8 more
TL;DR: In this paper, two compatible non-fullerene acceptors (IDIC and ITIC) with similar chemical structures and one new D-A-type polymer (PSTZ) donor were used to fabricate ternary PSCs.
Journal ArticleDOI

TL;DR: In this paper, a series of fused-ring electron acceptors (FREAs) based on indacenodithiophene (IDT) oligomers as cores are designed and synthesized, and effects of IDT number (1-3) on their basic optical and electronic properties are investigated.
Journal ArticleDOI
An easy and effective method to modulate molecular energy level of the polymer based on benzodithiophene for the application in polymer solar cells.
TL;DR: The polymer solar cells based on the polymer consisting meta-alkoxy-phenyl groups as conjugated side chain, PBT-OP, shows an enhanced open circuit voltage and thus higher efficiency of 7.50%, under the illumination of AM 1.5G, 100 mW/cm(2).
