中文摘要:
      用混和酸对碳纳米管进行功能化处理,并配制稀土改性碳纳米管悬浮液,通过自组装技术在单晶硅表面制备稀土改性碳纳米管复合薄膜。 XPS 和 SEM 检测结果表明:功能化处理后,碳纳米管表面含有羟基、羧基等官能团;稀土改性溶液中稀土的质量分数为 0 . 3% 时,对碳纳米管的改性效果最明显。 从吸收光谱可以看出,稀土改性碳纳米管复合薄膜在紫外-可见光区域均有吸收,特征峰相对密集在紫外光区域,能够拓展晶体硅太阳能电池的光谱响应范围。
英文摘要:
      Mixed acid was used to make the functionalization of carbon nanotubes( CNTs) and rare earth( RE) treated CNTs ( CNTs / RE) suspension was prepared. CNTs / RE-self-assembled monolayers ( CNTs / RE-SAM) was fabricated on the single-crystal silicon substrate by a self-assembling process. The testing results of XPS spectra and SEM images indicated that after CNTs was functionalized, it contained hydroxyl, carboxyl groups. The surface treatment effect of CNTs was most obvious when RE concentration was 0 . 3 wt% . From the absorption spectra, we found that CNTs / RE-SAM had absorption in the ultravioletvisible region, its absorption peaks were relatively in the ultraviolet region and the spectral response range of crystalline silicon solar cell wasexpanded.
