| 제목 | Efficient, thermally stable poly(3-hexylthiophene)based organic solar cells achieved by noncovalently fused-ring small molecule acceptors |
| 초록 | Organic solarcells (OSCs) based on poly(3-hexylthiophene) (P3HT) have achieved a significantenhancement of the power conversion efficiency (PCE), mainly driven by thedevelopment of nonfullerene small-molecule acceptors. However, their relativelypoor thermal stability, in terms of blend morphology and concomitantperformance, limits their application. Herein, we develop a non-covalentlyfused-ring acceptor (NFRA), denoted as CPDT–ICMe to achieve high-performanceand thermally stable P3HT-based OSCs. Non-covalent interactions in CPDT–ICMeimpart high planarity to its molecular backbone and facilitate strongintermolecular packing. A resulting P3HT:CPDT–ICMe OSC demonstrates superiorelectrical properties and a high PCE of 8.17%. Importantly, the P3HT:CPDT–ICMeOSC exhibits excellent thermal stability, maintaining 98.4% of initial PCEafter 100 h of thermal annealing at 120 C. |
