Dye adsorption on Ti02and electron transport in Ti02film are the two critical factors in determining efficiency of the the dye sensitized solar cell (DSSC). Increasing dye adsorption which increases the light harvesting is usually achieved by using nanoporous or nanoparticle Ti02films. Electron transport is determined by the inter-particle resistance of Ti02film. Electrospinning is a viable method for forming porous structure materials with high surface area. In this study, it was found that electrospinning is able to achieve good solar cell performance due to the high electron transport caused by the pores in the Ti02film.

Dye-sensitized solar cells (DSSCs) have been extensively studied due to their promising potential for high efficiency, low production cost and eco-friendly production. The photoanode of DSSCs is traditionally composed of randomly packed TiO2 nanoparticles which have large specific surface area and suitable band gap (3.2 eV) for the effective injection of electrons from the dye molecules to the semiconductor. However, its high surface charge recombination rate accounts for its low efficiency. Alternatively, silica which is chemically inert, thermally stable, high surface area, and inexpensive can be used to substitute TiO2 as photoanode material. However, bulk silica has a wide band gap of 8.9 eV and its band gap need to be narrowed in order to use it as photoanode materials. Thus, in this study, the effect of nanosilica photoanode and its particle size on the performance of dye sensitized solar cell are investigated and characterized. The result is then compared with the fumed silica and conventional TiO2 DSSCs. Although the results shows that photon-electron conversion is inferior compared to TiO2 photoanode, it has a great potential as the fabrication cost is low and more environmental friendly.Keywords : Dye Sensitized Solar Cell, Photoanode material, Nanosilica, Sol gel synthesis
