Annotation Dye Sensitized solar cell (DSSC) have been looked upon as having the potential to modernize photovoltaic as a cost effective technology. Especially nanostructured DSSC is proposed to have the capability to boost the efficiency by limiting charge recombination, thereby increasing the charge transportation which affects the overall conversion efficiency favourably. In the present work we discuss the effect of nanofibers as photo anode for increasing the efficiency of a dye sensitized solar cell. As we know nanostructured metal oxides have paying much attention in the field of photovoltaics due to their physical properties and dimensionality. This type of geometry provides direct and spatially separated charge transport channels for electrons and holes. TiO2 single-crystalline nanofibers of different diameter are prepared by electrospinning process and TiO2 nanoparticles by doctor blade technique are used for fabricating the device using natural sensitizers.
