N2 - In order to improve the energy conversion efficiency by applying the Al/Ru bilayer on a flat glass substrate of a counter electrode (CE), a 0.45 cm 2 dye-sensitized solar cell (DSSC) device with glass/FTO/ blocking layer/TiO2/N719 (dye)/electrolyte/(50 nm Ru-50 nm Al)/glass was prepared. For a comparison, a Ru CE of 100 nnrthickness on a flat glass substrate was also prepared using the same method. The photovoltaic properties, such as the short circuit current density (Jsc), open circuit voltage (Voc), fill factor (FF), energy conversion efficiency (ECE), and impedance, were characterized using a solar simulator and potentiostat. By Jsc, Voc, FF and ECE measurements, the ECE of the device with Al/Ru bilayer CE was 2.36%. The increase in efficiency was 1.46 times that of the device with a 100 nm Ru CE. The impedance at the interface between CE and the electrolyte decreased with Al/Ru bilayer films. The results imply that the application of an Al/Ru bilayer film improves the efficiency of DSSC devices.
