| 摘 要： | 以钛网作为基底,采用阳极氧化、氨气氮化的方法制备了TiN纳米管,随后电沉积CoSe,制备了CoSe/TiN/Ti同轴纳米管阵列电极。循环伏安结果表明,CoSe/TiN/Ti电极对I-3具有高的电催化还原性能,这归因于高催化活性的CoSe和高导电的TiN的协同效应。以CoSe/TiN/Ti电极作为对电极组装染料敏化太阳能电池,电池的能量转换效率高达9.25%,比传统Pt/FTO对电极组装的电池(8.09%)高1%。这一结果为非Pt对电极纳米结构的设计提供了一个很好的思路。

| Abstract: | Coaxial CoSe/TiN nanotube arrays have been designed for high performance counter electrodes of dye-sensitized solar ceils.This hybrid counter electrodewas prepared by electrodepositing CoSe into TiN nanotube arrays,which are prepared by anodization of a Ti mesh substrate and subsequent nitridation using ammonia annealing.The CoSe/TiN counter electrode displayed excellent performance comparable to Pt/FTO counter electrode due to the effectively combined network of both high electrical conductivity and more favorable and efficient interracial active sites.The energy conversion efficiency of the cell with CoSe/TiN/Ti as counter electrode reached 9.25％,which was superior to 8.09％ of the cell with Pt/FTO counter electrode under the same experimental conditions.These results demonstrate that the coaxial composite nanostructureis very promising for the structure-controllable counter electrode (CE) material. |
