Summary: The high trap density in organic solar cells is a major limitation for improving power conversion efficiencies. This study demonstrates that extending the donor core of nonfullerene acceptors from a heptacyclic unit to a nonacyclic unit efficiently reduces the trap density in the solar cells. This approach not only increases the mobility and inhibits charge-carrier recombination, but also achieves an impressive power conversion efficiency of 17.1% with a low nonradiative recombination energy loss.

Summary: Side-chain engineering plays a crucial role in optimizing Y-series nonfullerene acceptors (NFAs) for organic solar cells (OSCs). By investigating the orientation of side chains, it was found that the meta-positioned hexylphenyl group (m-BTP-PhC6) showed the most beneficial effects on optical absorption, intermolecular packing, and phase separation of NFAs, resulting in a device efficiency of 17.7% when paired with a donor polymer PTQ10. This study demonstrates that regulating side-chain orientations of Y-series NFAs is a promising strategy for achieving favorable morphology, high charge mobility, and improved solar cell performances.

Summary: Bulk-heterojunction active layers prepared by blend casting (BC) method have been widely used in organic/polymer solar cells (OSCs) for over two decades, showing high efficiencies and stability. Sequential deposition (SD) method, which coats donor and acceptor layers sequentially, has emerged as a promising strategy to optimize OSCs, especially with nonfullerene acceptors achieving power conversion efficiency (PCE) up to >18%. This method allows for separate engineering of different layers, leading to an ideal profile of vertical component distribution beneficial for charge generation, transport, and collection, as well as potential for constructing large-area solar cell panels.

Summary: This study designed a series of large-bandgap polymer donors and validated their device performances in all-polymer solar cells by combining them with a polymer acceptor, achieving high efficiency with a maximum of 15.8%. The systems showed more efficient charge transfer and less charge recombination as the energy-level offsets increased, leading to improved short-circuit current density, fill factors, and power conversion efficiency.

Summary: Ternary polymer solar cells offer advantages such as broader absorption bands and greater potential for micro-morphology regulation compared to binary PSCs. One potential configuration within ternary devices, involving one donor and two acceptors, shows promise in improving morphology stability of the active layer film. This could help overcome obstacles hindering the commercialization of PSCs.

Summary: The synthesis of symmetric or dissymmetric A-DA'D-A type non-fullerene small molecular acceptors (NF-SMAs) using a dissymmetric backbone and selenophene substitution on the central core leads to improved optical and electrical properties. Increasing the number of selenophene results in a red-shifted absorption, as well as larger electron mobility and crystallinity in the thin film. The combination of dissymmetric core and precise replacement of selenophene effectively enhances charge transport characteristics in binary polymer solar cells.
