| 摘 要： | 利用溶胶凝胶法合成10~20 nm的FTO颗粒,制备成FTO基底膜。运用离子交换法将Cu2S颗粒负载到FTO基底膜上,制备出FTO@Cu2S复合对电极。通过控制交换次数来调节Cu2S的负载量。封装电池光电性能测试结果表明,离子交换法制备的对电极可以有效降低电池的内部串阻,提高电池的填充因子,当交换次数为3时,电池的光电转换效率最高可达1.84%。

Research on Preparation and Performance of FTO@Cu2S Composite Counter Electrode |
| |
| Abstract: | FTO particles with the size of 10~20 nm were synthesized by sol-gel method, and the as-prepared FTO was fabricated to FTO substrate film. Cu2S nanoparticles were loaded on FTO film via ion exchange method to construct FTO@Cu2S composites counter electrodes. The amount of Cu2S was tuned by controlling times of ion exchange. The photoelectric properties of the sealed cells show that FTO@Cu2S composite counter electrode can significantly reduce internal resistance and increase the fill factor of the cell. When exchange time was 3, the cell can achieve the highest photoelectric conversion efficiency of 1.84%. |
