Incorporation of an Extended Electron‐Deficient Central Block Into Small‐Molecule Acceptors Toward Enhanced‐Performance Organic Solar Cells

open access: yesAggregate, Volume 7, Issue 6, June 2026.
Two novel extended electron‐deficient central cores (Tz‐Qx, Dz‐Qx) with F/Cl‐substituted terminal groups synergistically optimize small molecule acceptors. Tz‐Qx‐4F outperforms Dz‐Qx‐based counterparts, achieving 19.50% PCE (29.3 mA cm−2 JSC) when blended with D18, thus providing valuable insights for designing high‐performance organic solar cell ...
