Dual-Function Compatibilizers for Enhancing Both Performance and Long-term Stabilities of Organic Solar Cells |
| 초록 |
In this study, a novel acceptor–donor–acceptor (A–D–A) triad type molecule, 5TRh-PCBM, which has an oligothiophene segment as the central core and fullerene-derivatives as the end groups, is designed as a compatibilizer for enhancing the thermal stabilities and mechanical properties of efficient organic solar cells while increasing their power conversion efficiencies (PCEs). To examine the effectiveness of this molecular compatibilizer, OSCs with different donors (PTB7-Th, PBDB-T, and P3HT) have been fabricated and tested, with addition of various amounts of 5TRh-PCBM. The addition of 5 and 10 wt% of 5TRh-PCBM significantly enhance the thermal and mechanical stabilities of all tested PSCs. Our comprehensive investigations have revealed the effects of 5TRh-PCBM on the optical, morphological, photovoltaic, and mechanical properties of molecularly engineered OSCs. |
