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

Organic solar cells (OSCs) have been dominated by donor: acceptor blends based on
fullerene acceptors for over two decades. This situation has changed recently, with non …

Molecular design of non-fullerene acceptors is of vital importance for high-efficiency organic
solar cells. The branched alkyl chain modification is often regarded as a counter-intuitive …

The ternary strategy has been widely identified as an effective approach to obtain high‐
efficiency organic solar cells (OSCs). However, for most ternary OSCs, the nonradiative …

Manipulating the donor: acceptor (D: A) energetics, eg, the highest occupied molecular
orbital (HOMO) offset, is the key to balancing the charge separation and charge …

The ternary blend is demonstrated as an effective strategy to promote the device
performance of organic photovoltaics (OPVs) due to the dilution effect. While the …

Non-fullerene acceptors (NFAs) are currently a major focus of research in the development
of bulk-heterojunction organic solar cells (OSCs). In contrast to the widely used fullerene …

The chemical structure of donors and acceptors limit the power conversion efficiencies
achievable with active layers of binary donor-acceptor mixtures. Here, using quaternary …

The trade‐off between the open‐circuit voltage (Voc) and short‐circuit current density (Jsc)
has become the core of current organic photovoltaic research, and realizing the minimum …

The strategy of isomerization plays a simple and effective role in optimizing the molecular
