TiO2 nano-particle paste was prepared by ethyl cellulose, α-terpineol and bis(2-ethylhexyl) phthalate (dioxcyl phthalate) for dye-sensitized solar cells (DSSCs). Dispersion and absorbance of TiO2 photoanode films was controlled by adding different amount of ethyl cellulose and α-terpineol. The morphology of prepared TiO2 films was studied by field emission scanning electron microscopy (FE-SEM) and the optical properties of TiO2 films were measured by UV/vis spectra. Photovoltaic- current density was observed to determine the electrochemical response of DSSCs. Energy conversion efficiency was obtained about 7.1 % at ethyl cellulose and α-terpineol at optimal mixed ratio (as ethyl cellulose: 0.1 g; α-terpineol: 1.5 ml) under illumination with AM 1.5 (100 mWcm-2) simulated sunlight.
