In this review, we aim to explore the structure–property relationships of a library of Y-series
non-fullerene acceptors (NFAs), their current advances, and present systematic (chemical …

Given that bromine possesses similar properties but extra merits of easily synthesizing and
polarizing comparing to homomorphic fluorine and chlorine, it is quite surprising very rare …

The diverse molecular stacking tuned by peripheral halogens in non-fullerene acceptors
(NFAs) significantly affects the molecular physicochemical properties, the film morphologies …

Peripheral halogen regulations can endow non‐fullerene acceptors (NFAs) with enhanced
features as organic semi‐conductors and further boost efficient organic solar cells (OSCs) …

Recently, sequential layer‐by‐layer (LbL) organic solar cells (OSCs) have attracted
significant attention owing to their favorable p–i–n vertical phase separation, efficient charge …

In organic solar cells, the resulting device efficiency depends strongly on the local
morphology and intermolecular interactions of the blend film. Optical spectroscopy was used …

Non‐fullerene acceptors (NFAs) as used in state‐of‐the‐art organic solar cells feature highly
crystalline layers that go along with low energetic disorder. Here, the crucial role of energetic …

Organic photovoltaic cells using Y6 non-fullerene acceptors have recently achieved high
efficiency, and it was suggested to be attributed to the charge-transfer (CT) nature of the …

The solution state of a conjugated polymer plays a critical role in the film morphology and
charge carrier mobility of the solution process organic field-effect transistors (OFETs) …

The single bulk‐heterojunction active layer based on non‐fullerene acceptors (NFAs) has
dominated the power conversional efficiencies above 18% in state‐of‐the‐art organic solar …
