Successfully decreasing the voltage loss in natural photo voltaic cells (OSCs) is crucial to bettering the ability conversion effectivity (PCE) of OSCs. On this research, extremely environment friendly ternary OSCs had been constructed by including a non-fullerene acceptor Qx2 with a excessive open-circuit voltage (VOC) and low power loss (Eloss) into PM6:m-BTP-PhC6 primarily based binary gadgets. The third element Qx2 exhibits barely complementary absorption with m-BTP-PhC6 and in addition optimizes the molecular packing, orientation, and morphology of the lively layer. Furthermore, the incorporation of Qx2 diminished the energetic dysfunction and improved the electroluminescence quantum effectivity, which suppresses the Eloss and additional results in a better VOC than the PM6:m-BTP-PhC6 binary mix. Consequently, synergetic enhancements of VOC, brief circuit present (JSC), and fill issue (FF) are realized, ensuing within the PCE of 18.60%. This work exhibits that the choice of the suitable third element has optimistic implications for decreasing Eloss and bettering the PCE of OSCs.
