Water Composition-Tolerant Eco-Friendly Polymer Solar Cells based on C70-based Aqueous-Soluble Fullerene Acceptor |
| 초록 |
In this work, the development of an aqueous-processable C70-based fullerene derivative (PC71BO15) for eco-friendly polymer solar cells (eco-PSCs) processed by water/ethanol co-solvents is reported. The PCEs of PC71BO15-based eco-PSCs up to 2.51%, which is the highest value reported to date for water/ethanol processed PSCs, was achieved due to the promising aggregation characteristics and improved light absorbing ability. At the optimized water volume 15% co-solvent, the PCE of the PC71BO15-based eco-PSCs is 73% higher than that of the PC61BO15-based counterparts, as a result of enhanced light absorption. More importantly, the PC71BO15-based eco-PSCs show much higher tolerance in their PCEs to the water/ethanol composition. The PC71BO15-based eco-PSCs with eco/human-friendly aqueous processing in ambient conditions is able to have excellent photovoltaic performances scalability due to the promising water content-tolerance. |
