Incorporation of siloxane-functionalized units into polymers backbone has proven to be an efficient strate.y to improve photovoltaic performance. In this work, a low-cost siloxane-containing unit was developed to construct a series of te.polymers, and the effects of siloxane on the polymer performance were syste.atically studied. Different conte.ts of thiophene containing siloxane-functionalized side chain were introduced into PM6 to obtain a series of polymers(PM6, PM6-SiO-10, PM6-SiO-20 and PM6-SiO-30). The siloxane-functionalized side chains in polymers have only a slight effect on the absorption behavior and frontier molecular orbitals. However, when the siloxane conte.t increased, the te.polymers' aggregation property decreased and the te.perature-dependency increased, leading to improved donor-acceptor compatibility. The power conversion efficiency(PCE) based on PM6:Y6, PM6-SiO-20:Y6 and PM6-SiO-30:Y6 devices was 15.64%, 16.03% and 15.82%, respectively. In comparison, the active layer based on PM6-SiO-10:Y6 exhibits the most appropriate.phase separation morphology, resulting in effective exciton dissociation, more balanced hole-electron transport and less recombination. Consequently, the highest PCE of 16.69% with an outstanding shortcircuit current density of 26.96 mA·cm^(-2) was obtained, which are one of the highest values for siloxane-functionalized polymer-based *** work demonstrate. that finely controlling the conte.t of siloxane-functionalized thiophene is beneficial for obtaining high-performance te.polymer donors and provides a novel and low-cost method to improve photovoltaic performance.
