Copolymer-Templated Nitrogen-Enriched Carbon Nanomaterials for Highly Efficient Dye-Sensitized Solar Cells |
| 초록 |
Dye-sensitized solar cells (DSSCs) have attracted considerable interest because of their enhanced conversion efficiency and potential low costs of production and materials. On the basis of device engineering benefited from continuous efforts on material innovation and device physics, a state of the art DSSCs has achieved a validated efficiency of 12.3%. However, the components of conventional DSSCs should be developed and replaced with less expensive and eco-friendly materials for much-needed efficiency improvement and practical uses. Very recently, copolymer-templated nitrogen-enriched carbon nanomaterials (CTNCs) with tunable morphology were synthesized by the carbonization of well-defined block (PAN-b-PBA) copolymers to generate mesopores and used as metal-free conter electrodes in organic DSSCs. As a result, CTNCs exhibit electrocatalytic performance superior to Pt. Here, new materials paradigm and perspectives for high efficiency dye-sensitized solar cells will be described. |
