One of the greatest challenges facing humanity is alternative renewable energy instead of fossil fuels for electricity generation. Solar energy as an inexhaustible source can be the solution to the energy problem in the future. The conversion of solar energy into electricity relies on hotovoltaic devices, so-called solar cells. Dye-sensitized solar cells (DSSCs) is a type of solar cell. Although silicon based solar cells (inorganic cells) are widely used because of their high efficiency, they are rigid and manufacturing costs are high.DSSCs have attracted great interest as potential candidates of “low cost solar cells” in the solution of global energy demand .DSSCs comprise a sensitized semiconductor (photoelectrode) and a catalytic electrode (counter electrode) with an electrolyte sandwiched between them. The basic benefit of employing nanostructures in DSCs is that the photoelectrode films constructed with nanostructures are highly porous. It is therefore, compared to bulk material, nanostructures forming photoelectrodes can offer a larger surface area for dye adsorption, contributing to optical absorption and leading to an improvement in the solar cell conversion efficiency. The aim of this study was to evaluate the effect of the characteristics hotoelectrode layer on the efficiency DSSC.To fabricate nanofibers ,polyvinylpyrrolidone ,titanium isopropoxide, acetic acid , ethanol and silver nitrate were used. The as-fabricated TiO2/Ag composite nanofibers were calcinated to remove the PVP polymer and solvents,. Finally, Ag nanoparticle doped TiO2 nanorods for use in dye sensitized solar cells were prepared by mechanical treatments on obtained nanofibers. Nanoparticle paste and nanorods paste were used in solar cell.By using Taguchi orthogonal array table based on the number of levels and factors solar cells were fabricated; And efficiency of each them obtained by the results of the current / voltage test. The results showed that all the factors studied had a significant effect on the efficiency of solar cells.weight percent of the nanorods to nanoparticles of titanium dioxide, photoelectrode thickness and percentage of silver nitrate in the Electrospining solution, respectively, ranked first to third affect the efficiency of solar cells.the factors and levels that determine in this study showed solar cells with 0/36% silver nitrate in electrospinning solution and 25% weight of nano-rods titanium dioxide to nanoparticles and 2/81 ?m thickness had highest efficiency. Key words: dye sensitized solar cell, titanium dioxide nano-rod, Ag nanoparticle, Design Of Experiments.
