The area of nanostructured materials for dye
sensitized solar cells has gained great interest
especially after a breakthrough by Gratzel and
coworkers in developing a solar cell from
nanostructured oxide of titania gaining an overall
efficiency of about 11% [1–5]. Since then the
research has been going on with an emphasis on
further improvement on this achievement [6–8].
One area that is having a lot of interest is
improvement on the charge transfer characteristics
from the dye to semiconductor and hence in the
whole system. The approach in our research group
has been on synthesis of nanofibers of titania oxide
that can provide a directed transport of electrons to
the conducting back contact and hence giving
optimal electronic charge transport through the cell.
Titania nanofibers have been synthesised before
[9–11], but the reports have been inconclusive as to
what stage of synthesis the nanofibers form
