Abstract :
For dye-sensitized solar cells, titanium dioxide is a promising wide band gap semiconducting semiconductor. With typical nanoparticles, the poor electron transport qualities continue to be a problem. Here, in order to enhance the charge transport capabilities, we hydrothermally produced TiO2 nanorods and nanoparticles. With the use of X-ray diffraction and electron microscopy examination, the generated nanorods and nanoparticles' structural and morphological data was examined. With a device using nanorods and nanoparticles and less than 100 mW/cm2, a high power conversion efficiency of 7.7% is attained. According to the electrochemical impedance analysis, devices using synthetic TiO2 nanorods or nanoparticles have better electron transport properties than devices using commercial P25 nanoparticles.

Keywords : dye-sensitized solar cells, titanium dioxide, band gap semiconducting semiconductor, TiO2 nanorods and nanoparticles, electrochemical impedance analysis, electron transport properties.
