Copolymer-templated nitrogen-enriched nanocarbons as a low charge-transfer resistance and highly stable alternative to platinum cathodes for superior performance dye-sensitized solar cells |
| 초록 |
In this study, copolymer templated N-enriched nanocarbons (CTNCs) with well -controlled morphology, nanoporosity, and N-content were demonstrated as efficient and alternative metal-free counter electrodes (CEs) for dye-sensitized solar cells (DSSCs) based on the Co(bpy)32+/3+ redox couple. The observed activity is attributed to the combination of the high surface area of CTNCs afforded by a three-dimensional, hierarchical pore structure, and to their unique electronic properties stemming from the presence of nitrogen heteroatoms located on the edges of nanographitic domains. Altogether, the use of CTNC CEs enhanced the efficiency and fill factor (FF) of JK-306 dye, Co(bpy)3 2+/3+ redox couple based DSSCs up to 10.32% and 73.5%, respectively, suggesting the considerable promise of these materials as an attractive alternative to costly Pt-based CEs. |
