| Outline of Final Research Achievements |
Single-walled carbon nanotubes (SWNTs) are representative 1D nano-material and possess many exceptional properties. Many applications have bee proposed. In this project, we focus on two issues in SWNT research. First, we performed diameter and chirality controlled synthesis of SWNTs. Sub-nm vertically aligned SWNTs are obtained from Co-Cu catalyst, and (12,6) enriched SWNTs are successfully synthesized from sputter Co-W catalyst. Second, we introduced VA-SWNT in a solar cell as the replacement of metal transparent conductive electrode. The SWNTs based are found to be effective in a solar cell with power conversion efficiency of 10%. This value can be further improved to about 12% by putting a PMMA coating layer.
