  Electrospun TiO2 nanofibers were prepared by   electrospinning of the polymeric sol containing a titanium   precursor and Poly(vinyl acetate) in acetic acid-dimethyl   formamide mixture and subsequent sintering of the nanofibers at   500°C. The resultant continuous, polycrystalline porous   nanofibers contained TiO2 grains of 15--20 nm sizes.   The continuous TiO2 nanofibers were broken down into   nanorice grains via mechanical grinding. Morphology and crystal   structure of the resulting nanofibers and nanorice grains were   characterized by scanning electron microscopy (SEM) and X-ray   diffraction analysis (XRD), respectively. Photovoltaic properties   of dye-sensitized solar cells (DSSC) fabricated from the   nanofibers and nanorice grains, showed superior performance with   the latter.
