Self-sorting of Metallic Carbon Nanotubes for High Performance Large Area Low Cost Transparent Electrodes Investigators
نویسنده
چکیده
Objective This project is investigating the use of carbon nanotubes (CNT) for transparent conducting electrodes in photovoltaic applications. In order to decrease the sheet resistance, both the electronic properties of the CNTs – namely the tube conductivity and tube-to-tube contact resistance – and the sheet morphology have to be controlled. This research aims to reach this target through the development of solution-based processes to simultaneously separate metal from semiconductor nanotubes using specific surface functional groups (such as aminoand phenyl-silanes on SiO2 substrates) and control the alignment of the CNTs into bundles during spin-coating deposition. CNT doping methods are also being investigated to further improve the sheet conductivity.

Project title : Self - sorting of Metallic Carbon Nanotubes for High Performance
SWNTs have superb electronic and mechanical properties; however, SWNTs come in different chiralities making them either metallic (MET) or semiconducting (SC). It is desirable to have only MET tubes in transparent electrode applications. We have recently developed a method to selectively separate the SC and MET SWNTs and form self sorted networks of each on different functionalized surfaces. To ...
