Abstract

This article provides an overview of the electrical impedance spectroscopy (EIS) analysis that has utilized to characterize photo-electrochemical prominence of dye-sensitized solar cells (DSSCs) prepared by various postdeposition treatments. Hot-compression technique has been found as an effective postdeposition treatment compared to compression and without compression for ZnO-based DSSC. In detail analysis of the electron transport data has been presented and analyzed in a different way to support the photocurrent-voltage, structural and scanning electron microscopy image data for the cells prepared by various postdeposition treatments. EIS analysis has been described using Nyquist plot, bode plot, impedance vs frequency plot, dielectric effect and electric modulus effect for the cells prepared by those three postdeposition treatments.
