The production rate by this multi-nozzle approach is several times higher than that of the single-nozzle electrospinning. The nanofibers produced were having a short range of diameters similar to the case of nanofibers produced by single nozzle electrospinning. The well-aligned nanofibers are subsequently processed into vertically oriented SnO 2 nanowires on an FTO substrate. The average diameter and length of the wires were 75 ± 25 nm and 19 ± 2 μm, respectively. Dye-sensitized solar cells using this nanostructured material as the working electrode yielded a short-circuit current density (J sc) of 9.9 mA cm -2 (which is 42% higher than that achieved by nanowires produced by other methods), an open-circuit voltage (V oc) of 0.525 V and a power conversion efficiency (η) of 2.53%. We believe that improvement of the multi-nozzle electrospinning is highly promising for commercialization due to simplicity and easiness of fabricating the spinneret, control over the diameter and spatial orientation of the fibers. © 2012 The Royal Society of Chemistry.||Source Title:||Journal of Materials Chemistry||URI:||http://scholarbank.nus.edu.sg/handle/10635/84776||ISSN:||09599428||DOI:||10.1039/c1jm15047b|
