Benzoxadiazole derivatives have been rarely employed in designing non-fused ring
electron acceptors (NFREAs). Herein, two novel NFREAs consisting of uniform …

Dihalogenated 1, 1-dicyanomethylene-3-indanone (IC) plays a key role in top-performing
fused-ring electron acceptor (FREA)-based polymer solar cells (PSCs). Here, we first …

Halogenation, for example, fluorination and chlorination, is an effective strategy to regulate
the performance of organic photovoltaic materials. Although fluorination has been widely …

The morphology of a bulk heterojunction (BHJ) blend within a polymer solar cell (PSC)
device plays a crucial role in its performance. The ideal morphology is generally achieved …

Developing non-fused-ring electron acceptors (NFREAs) is a promising strategy toward high-

It has been reported that the length of branched alkyl side chains on fused-ring electron
acceptors confers different impacts on properties versus solubility of BJH blends. However …

Fused‐ring electron acceptors with acceptor‐donor‐acceptor (A‐D‐A) structure have
become a hot research field in recent years. In this work, 2, 1, 3‐benzoxadiazole (BO) and 2 …

Fluorine (F) substitution on conjugated polymers in polymer solar cells (PSCs) has a diverse
effect on molecular properties and device performance. We present a series of three DA type …

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 …

Organic solar cells (OSCs) based on nonfused ring electron acceptors (NFREAs) have
shown great potential for future commercial applications due to their reduced synthesis …
