Chlorinated polymerized small molecule acceptor enabling ternary all-polymer solar cells with over 16.6％efficiency
文献摘要：
Recently,all-polymer solar cells(all-PSCs)based on polymerized small molecule acceptors(PSMAs)have achieved significant progress.Ternary blending has proven to be an effective strategy to further boost the power conversion efficiency(PCE)of the all-PSCs.Herein,a new A-DA'D-A small-molecule acceptor-based PSMA(named as PYCl-T)was designed and synthesized,which possesses similar polymer backbone with the widely used PY-IT,but with chlorine substitution on the A-end groups in the A-DA'D-A structure.PYCl-T was then employed as the third component into the PM6:PY-IT system and the ternary all-PSCs based on PM6:PY-IT:PYC1-T demonstrated a high PCE of 16.62％(certified value of 16.3％).Moreover,the PCE of 15.52％was realized in the enlarged ternary all-PSCs with effective area of 1 cm2,indicating the great potential in large-scale applications.Moreover,the optimized ternary blend films of PM6:PY-IT:PYC1-T show excellent thermal stability at 150℃.This work demonstrates that the utilization of a ternary blend system involving two well-compatible PSMA polymer acceptors is an effective strategy to boost the performance of the all-PSCs.
