Abstract
nano-particle paste was prepared by ethyl cellulose, -terpineol and bis(2-ethylhexyl) phthalate (dioxcyl phthalate) for dye-sensitized solar cells (DSSCs). Dispersion and absorbance of photoanode films was controlled by adding different amount of ethyl cellulose and -terpineol. The morphology of prepared films was studied by field emission scanning electron microscopy (FE-SEM) and the optical properties of 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 -terpineol at optimal mixed ratio (as ethyl cellulose: 0.1 g; -terpineol: 1.5 ml) under illumination with AM 1.5() simulated sunlight.
