Abstract

The effect of morphology of anatase TiO2 nanoparticles as photoanode in dye sensitized solar cells (DSSCs) has been investigated. Two types of TiO2 nanostructures, namely nanograss and nanospherical particles, used in this study have been prepared via liquid phase deposition (LPD) method. Electrochemical impedance spectroscopy (EIS) analysis of DSSCs device with a sandwich structure of ITO/TiO2/dye/electrolyte/ Pt film indicated that the device utilizing TiO2 nanograss exhibited the lower in charge transfer resistance (Rct), of 49.1 μ. This might be due to the high-porous characteristic of TiO2 nanograss compared to the nanospherical particles that provides facile charge transport and ion diffusion. Power conversion efficiency as high as 0.97% has been recorded from the device utilizing nanograss of TiO2, which was 3 times higher compared to TiO2 nanospherical particles of which its conversion efficiency was only 0.33%.
