    • A very thin film of TiO2 was used to make dye sensitized solar cell (DSSC). To study the interfacial electron transfer between substrate and TiO2 layer, the photoelectrode was modified with carbon nanotubes (CNT) and carbon nanofibers (CNF), which have excellent electrical conductivities and good chemical stability. The correlation between the properties of the modified interface and the morphology of the electrode were studied by Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM). Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS), X-ray Diffraction (XRD) and UV/VIS spectroscopy were used for the characterization of modified photoelectrode. The performance of the DSSC was measured by photocurrent-voltage curve.
