To extend the absorption and enhance the electron mobility of fused-ring electron acceptors
(FREAs), we designed and synthesized new FREAs (TTIC and TTIC-M) based on 4, 9 …

Nonfullerene-based organic solar cells (OSCs) have made a huge breakthrough in the
recent years. Introducing a proper side chain on the π-conjugated backbone plays a vital …

Fine tuning the end groups of non-fused ring electron acceptors (NFREAs) is one of the
effective methods to reduce energy loss in organic solar cells (OSCs) and thus realize high …

To develop the low‐cost nonfullerene acceptors (NFAs), two fully non‐fused NFAs (TBT‐2
and TBT‐6) with ortho‐bis ((2‐ethylhexyl) oxy) benzene unit and different side chains onto …

Abstract We report 4, 4‐difluoro‐4H‐cyclopenta [2, 1‐b: 3, 4‐b′] dithiophene (fCDT) as a
new electron‐rich unit to design polymer electron acceptors. Owing to the fluoro substitutes …

Dimeric fused-ring electron acceptors (DFREAs) have attracted much attention due to the
combined advantages of their monomeric and polymeric acceptors, including a well-defined …

In recent years, significant progress has been witnessed in organic solar cells (OSCs), which
is mainly attributed to the new active layer materials design, especially fused ring acceptors …

Asymmetric acceptor–donor–acceptor (ADA)-type fused-ring electron acceptors (FREAs)
have recently attracted increasing interest due to their excellent photovoltaic properties …

Nonfused electron acceptor based organic solar cells (OSCs) have garnered increasing
curiosity, because of their simple synthetic route and versatile chemical modification …

Side chain isomerization has shown significant influence on the intermolecular interaction
and aggregation morphology of organic small molecule acceptors. In this work, two isomeric …
