Non‐Fullerene Acceptors With A2 = A1‐D‐A1 = A2 Skeleton Containing Benzothiadiazole and Thiazolidine‐2,4‐Dione for High‐Performance P3HT‐Based Organic Solar Cells
Bo Xiao,Bo Xiao,Ailing Tang,Linxiu Cheng,Linxiu Cheng,Jianqi Zhang,Zhixiang Wei,Qingdao Zeng,Erjun Zhou +8 more
TL;DR: In this article, two planar small molecule acceptors (SMAs) with A2 = A1-D-A1 = A2 skeleton are designed and synthesized, where indacenodithiophene (IDT), benzothiadiazole (BT), and thiazolidine-2,4-dione (TD) are used as the central donor unit of D and the end group of A2, respectively.

Indene−C60 Bisadduct: A New Acceptor for High-Performance Polymer Solar Cells
TL;DR: A new soluble C(60) derivative, indene-C( 60) bisadduct (ICBA), with a LUMO energy level 0.17 eV higher than that of PCBM is synthesized and indicates that ICBA is an alternative high-performance acceptor and could be widely used in high- performance PSCs.
