Suppressing the non-radiative loss in organic solar cells (OSCs) through molecular design remains a significant challenge. Typically, triplet state of semiconductors is lower than charge transfer (CT) state, contributing to substantial via state. Herein, set terpolymers prepared by introducing simple Pt complex block into PM6 polymer backbone. These metalated exhibit high energy (ET1) and small singlet-triplet gap (∆EST), facilitating fast intersystem crossing (ISC) process generate excitons. Consequently, show enhanced exciton lifetime diffusion length, most importantly, effectively suppress recombination terminal channels. Moreover, modifies aggregation polymer, hence optimizing morphology active blends. The PM6-Pt1:L8-BO devices achieve champion power conversion efficiency (PCE) 18.54% (certified as 18.32%), highest reported for date. PCE further increased record 19.24% PM6-Pt1:PM6:L8-BO (0.8:0.2:1.2, wt/wt/wt) ternary devices. Overall, this work provides feasible approach designing with ET1, thereby reducing OSCs.

Modulating self-aggregation and charge transport in the upper acceptor layer of pseudo planar heterojunction (PPHJ) is crucial for enhancing dielectric constant suppressing trap density, leading to efficient stable organic photovoltaics (OPVs). In this work, a metal complex (MCA), PtAC-Cl, selectively incorporated into host Y6 PPHJ regulate morphology fill states. There exists strong chemical interaction between PtAC-Cl Y6, which can promote electron transfer. extend exciton diffusion length resulting enhanced reduced energetic disorder. Consequently, layer-modulated devices with achieved significant power conversion efficiency 18.16%. The universality also demonstrated PM6/eC9 PM6/L8-BO systems, achieving highest PCEs 18.79 19.30%, respectively. All improved are mainly attributed factor (FF) short circuit current (J
