Carbon nanotubes (CNTs) with different diameters as a counter electrode to fabricate dye-sensitised solar cells with high conversion efficiency are investigated. The CNT electrodes with large diameter demonstrated better redox reaction and higher energy conversion efficiency.
Field emission (FE) properties of individual single-walled carbon nanotubes (SWCNT) were investigated inside a field emission-scanning electron microscopy. The individual SWCNT turned on a voltage of 23V defined to produce a current of 10pA, and was saturated at around 43V and 880nA. The FE characteristic of individual SWCNT also followed a conventional Fowler–Nordheim (F–N) theory in which a single...
