Symmetric conjugated molecules can be broken through suitable synthetic strategies to
construct novel asymmetric molecules, which can largely broaden the material library. In the …

The power conversion efficiencies (PCEs) of organic solar cells (OSCs) have been greatly
improved with the rapid development of non-fullerene acceptors (NFAs) in recent five years …

Narrow bandgap n‐type organic semiconductors (n‐OS) have attracted great attention in
recent years as acceptors in organic solar cells (OSCs), due to their easily tuned absorption …

The majority of organic semiconductors have a low relative dielectric constant (εr< 6), which
is an important limitation for organic solar cells (OSCs). A high dielectric constant would …

Symmetry breaking provides a new material design strategy for nonfullerene small molecule
acceptors (SMAs). The past 10 years have witnessed significant advances in asymmetric …

This article is written from an organic chemist's point of view and provides an up‐to‐date
review about organic solar cells based on small molecules or oligomers as absorbers and in …

Organic photovoltaic cells (OPVs) are a promising cost-effective alternative to silicon-based
solar cells, and possess light-weight, low-cost, and flexibility advantages. Significant …

Although fullerenes and their derivatives, such as PCBM, have been the dominant electron-
acceptor materials in organic photovoltaic cells (OPVs), they suffer from some …

A novel small molecule, FBR, bearing 3-ethylrhodanine flanking groups was synthesized as
a nonfullerene electron acceptor for solution-processed bulk heterojunction organic …
