Thiophene with siloxane-functionalized side chain unit was synthesized and introduced into polymer PM6 to fine-tune morphology of the active layer of OSCs and obtain outstanding
J
SC
. The PM6-SiO-10:Y6 active layer exhibits the most appropriate phase separation morphology and obtained the PCE of 16.69%
which is one of the highest value for siloxane-functionalized polymer-based binary OSCs.
Incorporation of siloxane-functionalized units into polymers backbone has proven to be an efficient strategy to improve photovoltaic performance. In this work
a low-cost siloxane-containing unit was developed to construct a series of terpolymers
and the effects of siloxane on the polymer performance were systematically studied. Different contents 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 content increased
the terpolymers’ aggregation property decreased and the temperature-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 short-circuit current density of 26.96 mA·cm
−2
was obtained
which are one of the highest values for siloxane-functionalized polymer-based devices. This work demonstrates that finely controlling the content of siloxane-functionalized thiophene is beneficial for obtaining high-performance terpolymer donors and provides a novel and low-cost method to improve photovoltaic performance.
