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

Ternary blend organic solar cells (TB‐OSCs) incorporating multiple donor and/or acceptor
materials into the active layer have emerged as a promising strategy to simultaneously …

Polythiophenes (PTs) are promising electron donors for organic solar cells (OSCs) due to
their low production cost. However, the device performance of PTs in OSCs is rather poor …

A robust hole transporting layer (HTL), using the cost‐effective Cobalt (II) acetate
tetrahydrate (Co (OAc) 2⋅ 4 H2O) as the precursor, was simply processed from its aqueous …

Organic solar cells (OSCs) are emerging as a new photovoltaic technology with the great
advantages of low cost, light-weight, flexibility and semi-transparency. They are promising …

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 …

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

High voltage loss (V loss) limits further improvements of organic solar cells (OSCs), and thus
developing effective approaches to reduce V loss is important. Herein, a solvent additive …

In the last few decades, organic solar cells (OSCs) have drawn broad interest owing to their
advantages such as being low cost, flexible, semitransparent, non-toxic, and ideal for roll-to …

Herein, by using two fluorinated and chlorinated monomers with similar structures in
different molar ratios and dithieno [3′, 2′: 3, 4; 2 ″, 3 ″: 5, 6] benzo [1, 2-c][1, 2, 5] …
