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

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

During past several years, the photovoltaic performances of organic solar cells (OSCs) have
achieved rapid progress with power conversion efficiencies (PCEs) over 18 …

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 …

There is an urgent demand for all-polymer organic solar cells (AP-OSCs) to gain higher
efficiency. Here, we successfully improve the performance to 16.09% by introducing a small …

Herein, we synthesized new hetero‐halogenated end groups with well‐determined
fluorinated and chlorinated substitutions (o‐FCl‐IC and FClF‐IC), and synthesized …

Halogenation of nonfullerene acceptors (NFAs) is a general and effective strategy to
improve the power conversion efficiencies (PCEs) of organic solar cells (OSCs). Although …

The central unit (benzo [c][1, 2, 5] thiadiazole) in Y6 series of molecules plays a determining
role in their unique intermolecular packing for a three-dimensionally (3D) network, largely …

Side-chain engineering has been shown to be an important strategy to optimize Y-series
nonfullerene acceptors (NFAs). Most previous reports were focusing on changing the …

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