C70-based Water/Ethanol-Soluble Fullerene Acceptor for Solvent Composition-Tolerant Performance of Eco-Friendly Polymer Solar Cells |
| 초록 |
Eco-friendly polymer solar cells (eco-PSCs) based on aqueous-soluble conjugated materials have received great attention. In this work, the development of a C70-based fullerene (PC71BO15) for eco-PSCs processed by water/ethanol is reported. The PCEs of fabricated eco-PSCs up to 2.51%, which is the highest value for aqueous-processed PSCs, was achieved thanks to the promising aggregation behavior and enhanced light absorption ability. The optimized PCE of the PC71BO15-based eco-PSCs is 73% higher than that of the PC61BO15-based. Also, the PC71BO15-based eco-PSCs show much greater tolerance in their PCEs to the water/ethanol composition. PC71BO15-based eco-PSCs at a 30:70 water/ethanol ratio maintain 89% of the optimal performance, whereas only 45% for PC61BO15-based devices. Different aggregation behaviors induced large difference in terms of water-tolerant behavior, which is explored by several characterizations. The PC71BO15-based eco-PSCs with aqueous processing can ensure excellent reproducibility. |
