Organic photovoltaics (OPVs) have progressed steadily through three stages of photoactive
materials development:(i) use of poly (3-hexylthiophene) and fullerene-based acceptors …

With the emergence of ADA'DA‐type (Y‐series) non‐fullerene acceptors (NFAs), the power
conversion efficiencies (PCEs) of organic photovoltaic devices have been constantly …

The photoactive layer of organic solar cells consists of p-type electron donors and n-type
electron acceptors, which phase separate to form fine and continuous networks for charge …

At present, high-performance organic photovoltaics mostly adopt a bulk-heterojunction
architecture, in which exciton dissociation is facilitated by charge-transfer states formed at …

The structural order and aggregation of non‐fullerene acceptors (NFA) are critical toward
light absorption, phase separation, and charge transport properties of their photovoltaic …

A record power conversion efficiency (PCE) of over 19% is realized in planar‐mixed
heterojunction (PMHJ) organic solar cells (OSCs) by adopting the asymmetric selenium …

Vibrant research has demonstrated that the layer-by-layer (LBL) approach can achieve a
preferable vertical microstructure; however, the lack of precise control over vertical …

The power conversion efficiencies (PCEs) of small-molecule acceptor (SMA)-based organic
solar cells (OSCs) have increased remarkably, but their long-term stability is insufficient for …

Morphology is of great significance to the performance of organic solar cells (OSCs), since
appropriate morphology could not only promote the exciton dissociation, but also reduce the …

Although the recent development of Y-series small-molecule acceptors (SMAs) has led to a
dramatic increase in the power conversion efficiency (PCE) of organic solar cells (OSCs) …
