Abstract
To apply for the working electrode of dye-sensitized solar cell (DSSC), semiconducting TiO2 powder is deposited on indium tin oxide (ITO)-coated glass. In conventional DSSC fabrication, the high-temperature sintering process should be contained to make the necking of powders, and to assemble powders and substrate. In this research, dry TiO2 powder is deposited using a nano particle deposition system (NPDS) to make photoelectrode layer through spraying at room temperature conditions. The powder is sprayed through a slit-type nozzle having a 0.4×10mm2 rectangular outlet under atmospheric chamber pressure. Through XRD analysis and FE-SEM observation, the deposition of the semiconductor oxide powder is confirmed and the thickness (7.6μm) is measured. The fabricated DSSC has a short circuit current density JSC = 3.077mA/cm2, open circuit voltage VOC = 0.709V, and energy efficiency η = 1.24%.
