Abstract
Abstract: A new type of counter electrode (CE), composed of hydrophilic carbon (HC) particle and TiO2 colloid (HC/TiO2), was successfully prepared using doctor blade technique on fluorine-doped tin oxide substrate for dye-sensitized solar cell (DSSC). Properties of HC/TiO2 CE, including crystal structure, surface morphology, roughness, conductivity, and catalytic activity, were analyzed. Results showed that a HC/TiO2 CE with an average thickness of 1 µm contributed to high surface roughness. Cyclic voltammetry further revealed that HC/TiO2 CE displayed good catalytic activity similar to that of Pt electrode, which is mainly attributed to an addition of TiO2 in the electrode. DSSC was fabricated with HC/TiO2 CE. Under one sun illumination (AM 1.5, Pin of 100 mWcm−2), the device exhibited an energy conversion efficiency of 1.9 %, which is comparable to 3.6 % of the cell with Pt electrode under the same experimental conditions. These findings suggest that HC/TiO2 CE is a promising alternative CE for low-cost DSSCs. Graphical Abstract: [Figure not available: see fulltext.
