Multiporous Nanofibers of SnO2 by Electrospinning for High Efficiency Dye-Sensitized Solar Cells

Various one-dimensional nano-morphologies, such as multiporous nanofibers (MPNFs), porous nanofibers (PNFs), and nanowires (NWs) of SnO2, are synthesized using electrospinning technique by controlling the tin precursor concentration. The MPNFs have [similar]8-fold higher surface area compared to the...
