Abstract

Electron diffusion, recombination and transportation inside nanoporous ZnO-based dye-sensitized solar cell play an important role in photovoltaic efficiency and stability. In this research work, electrochemical impedance spectroscopic is used to investigate the ionic mechanisms inside the cell. An appropriate equivalent circuit model has also been modelled to interpret the impedance spectra and frequency response of the circuit. Three impedance spectra regions provide further information of the electrons kinetics and energy of the solar cell. The cell parameters such as the electron lifetime, τeff of 6.36 ms was measured as much shorter than TiO 2-based DSSC (25 - 160 ms), effective electron diffusion coefficient, Deff of 4.7e-7 cm2s-1 and effective rate constant for recombination keff of 157 s-1 have been analyzed accordingly. The highest overall power conversion efficiency was up to 2.45 %. The results and analysis proved the previous work on the nanotechnology fabrication of the dye-sensitized solar cell.
