“…In another case, Ge et al introduced benzodithophene (BDT) into the A-DA 0 D-A molecular template and synthesized four new acceptors with different end-groups. 108 Thanks to the good symmetry, highly delocalized p-conjugation, and excellent planarity of BDT, these molecules exhibit high electron mobility and ultra-narrow bandgap, and among them, X94FIC blended with PBDB-T displays a photo-response to 1000 nm, leading to a high J SC of 14.67 mA cm À2 and a champion PCE of 7.08%.…”

“…544 Similar to the Y-series, the A−(DA′D)−A approach was introduced in nonacyclic NFAs, as realized in structures 9-52−9-55 by the insertion of additional benzene rings replacing the thienothiophenes with benzodithiophene units. 555 in combination with PBDB-T. While 9-52, 9-53, and 9-55 revealed rather similar optical band gap values between 1.25 and 1.30 eV, 9-54 possesses an optical band gap of 1.45 eV due to a significantly upshifted LUMO level (−3.80 eV).…”

Organic solar cells are on the dawn of the next era. The change of focus toward non-fullerene acceptors has introduced an enormous amount of organic n-type materials and has drastically increased the power conversion efficiencies of organic photovoltaics, now exceeding 18%, a value that was believed to be unreachable some years ago. In this Review, we summarize the recent progress in the design of ladder-type fused-ring non-fullerene acceptors in the years 2018–2020. We thereby concentrate on single layer heterojunction solar cells and omit tandem architectures as well as ternary solar cells. By analyzing more than 700 structures, we highlight the basic design principles and their influence on the optical and electrical structure of the acceptor molecules and review their photovoltaic performance obtained so far. This Review should give an extensive overview of the plenitude of acceptor motifs but will also help to understand which structures and strategies are beneficial for designing materials for highly efficient non-fullerene organic solar cells.

Organic solar cells (OSCs) have entered the era of non-fullerene electron acceptors. Nowadays with the rapid development of non-fullerene electron acceptor materials, Organic photovoltaic show huge potential in challenging conventional photovoltaic technology. Among the emerging non-fullerene electron acceptors, the Y-series acceptors own superior performance. The single-junction devices based Y-series acceptors have achieved power conversion efficiencies of 17∼18%. This paper gives an overview of the recent advances of Y-series electron acceptors. Through discussing the selected molecules, the perspective of molecular design on three parts of the molecules, including the central core, side chain and end group, are spotlighted, and the photoelectric properties, photovoltaic performance and film morphology of various Y-series acceptors materials are also presented. Finally, some molecule design directions will be proposed to further promote the progress of OSCs.
