Carbon nanotube/silicon solar cells are very promising with photo-conversion efficiencies up to 15%.In these cells, a semi-transparent carbon nanotube film is deposited at room temperature on a n-doped silicon wafer, thus giving rise to an overall reduction of the total
Minimized lithium trapping by isovalent isomorphism for …
Silicon demonstrates great potential as a next-generation lithium ion battery anode because of high capacity and elemental abundance. However, the issue of low initial Couloic efficiency needs to be addressed to enable large-scale appliions. There are mainly two mechanisms for this lithium loss in the first cycle: the formation of the solid electrolyte interphase and lithium trapping in
