New Triad-Type, Multi-Functional Compatibilizers for Enhancing Device Efficiency and Thermal/Mechanical Stabilities of Polymer Solar Cells |
| 초록 |
In this work, we report a new acceptor–donor–acceptor (A–D–A) triad-type small molecule, 5TRh-PCBM, for use as a compatibilizer in enhancing the thermal stabilities and mechanical properties of efficient polymer solar cells (PSCs). This multifunctional 5TRh-PCBM molecule, consisting of an oligothiophene segment as the central core and fullerene derivatives as the end groups, is designed to enable strong interactions between the 5TRh-core with various types of efficient polymer donors containing thiophene or fused-thiophene units, while the end fullerene groups preferentially interact with PCBM acceptors. To examine the effectiveness of this molecular compatibilizer, PSCs with different donors (PTB7-Th, PBDB-T, and P3HT) have been fabricated and tested, with the addition of various amounts of 5TRh-PCBM. The addition of 5 and 10 wt% of 5TRh-PCBM significantly enhances the thermal and mechanical stabilities of all these PSCs. |
