Abstract Cathode interface layers (CILs) are crucial for optimizing the power conversion efficiency (PCE) and stability of organic solar cells (OSCs). Two small molecule CILs, PDINN‐TS PDINN‐BS developed, by modifying bay sites perylene diimide (PDI) with thieno [3,2‐b] thiophene 2,2′‐bithiophene, separately. Due to better electron‐donating capacity longer conjugate length exhibits a stronger self‐doping effect superior compatibility compared PDINN‐TS. Consequently, in PM6: Y6 OSCs, achieved an elevated PCE 16.95%, surpassing 16.66%. Meanwhile, excellent universality. When employing BTP‐eC9 PM6:L8‐BO systems, PDINN‐BS‐based device yielded 18.02% 18.95%, outperforming 17.51% 18.38%, respectively. Furthermore, tests revealed that after being stored glovebox 1500 h, retained 90% its pristine PCE, 86% showed 80% decay (T 80 ) 150 h air, 200 at 70 °C heating N 2 , 500 under 1 sun immersion, 120, 130, 380 This demonstrates displayed complicated environment. this study provides significative guidance exploitation high‐performance high‐stability OSCs.
