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

As the most classic electron-accepting building block, 2, 1, 3-benzothiadiazole (BT) and the
derived structures have achieved great success to construct photovoltaic materials …

The limited selection pool of high‐performance wide bandgap (WBG) polymer donors is a
bottleneck problem of the nonfullerene acceptor (NFA) based organic solar cells (OSCs) that …

Raising the lowest unoccupied molecular orbital (LUMO) energy level of Y‐type non‐
fullerene acceptors can increase the open‐circuit voltage (Voc) and thus the photovoltaic …

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 …

Typical organic photovoltaic materials show high Urbach energies (ca. 25–50 meV), which
is considerably higher than those of their inorganic counterparts and limits further …

Surmounting complicated defects at the electron transport layer (ETL) and perovskite
interface plays a non‐trivial role in improving efficiency and stability of perovskite solar cells …

Emerging nonfullerene acceptors (NFAs) with crystalline domains enable high-performance
bulk heterojunction (BHJ) solar cells. Thermal annealing is known to enhance the BHJ …

The end-cap** group (EG) is the essential electron-withdrawing component of
nonfullerene acceptors (NFAs) in bulk heterojunction (BHJ) organic solar cells (OSCs). To …

Despite the dihalogenation of terminals being an effective strategy to produce efficient
nonfullerene acceptor (NFA)-based organic solar cells (OSCs), hetero-dihalogenated …
