Side-Chain Length Modulation in Thieno[3,2‑c]isochromene Small-Molecule Donors for High-Performance Ternary Fullerene Organic Solar Cells
Side-chain engineering is an effective strategy for precisely tuning the crystallinity and active-layer morphology of high-performance bulk-heterojunction (BHJ) organic solar cells (OSCs). To systematically elucidate the side-chain length–property relationship across a complete homologous series, we herein designed and...
