High power conversion efficiency (PCE) and long-term stability are important requirements for commercialization of organic solar cells (OSCs). In this study, we demonstrate efficient (PCE = 18.60%) stable (t80% lifetime > 4000 h) OSCs by developing a series dimerized small-molecule acceptors (DSMAs). We prepared three different DSMAs (DYT, DYV, DYTVT) using linkers (i.e., thiophene, vinylene, thiophene– vinylene– thiophene), to connect their two Y-based building blocks. find that the crystalline properties glass transition temperature (Tg) can be systematically modulated linker selection. A DYV-based OSC achieves highest PCE (18.60%) among DSMA-based owing appropriate backbone rigidity leading an optimal blend morphology high electron mobility. Importantly, also demonstrates excellent operational under 1-sun illumination, i.e., t80% 4005 h.

Therefore, it challenging improve performance all-PSCs. Herein, a ternary strategy adopted modulate an blend, in which PM6:PY-82 selected as host blend PY-DT employed guest component.
