Sidechain engineering as an efficient and convenient strategy has been widely used to optimize molecular structure of photovoltaic materials for boosting power conversion efficiency(PCE) of organic solar cells(OSCs). Herein, a new Y-series acceptor named Y-ThSi with trialkylsilyl-substituted thiophene as conjugated sidechain is developed. Compared with its parental Y6 with multiple intermolecular interactions, Y-ThSi has a unitary molecular packing due to the additional steric hindrance from twodimensional(2D)-conjugated trialkylsilyl-thiophene. Therefore, Y-ThSi shows an obviously blue-shifted absorption with an onset of ～850 nm but significantly up-shifted lowest unoccupied molecular orbital energy level. For the PM6:Y-ThSi pair, the spin-coating OSCs achieve a decent PCE of 14.56% with an impressively high photovoltage(VOC) of 0.936 V. Inspired by its high VOCand narrow absorption, Y-ThSi is introduced into near-infrared absorbing binary PM6:BTP-eC9 host to construct ternary OSCs. Thanks to the complementary absorption, optimized morphology, and minimized energy loss properties, the PM6:BTP-eC9:Y-ThSi-based OSCs offer a higher PCE of 18.34%. Moreover, our developed strategy can overcome the commonly existed PCE drop when the blade-coating towards large-scale printing is used instead. Therefore, a comparable PCE of 18.34% is achieved, which is one of the best values for the blade-coating OSCs so far.
