Electrochemical Impedance Spectra of Dye-Sensitized Solar Cells: Fundamentals and Spreadsheet Calculation

Abstract EN

Electrochemical impedance spectroscopy (EIS) is one of the most important tools to elucidate the charge transfer and transport processes in various electrochemical systems including dye-sensitized solar cells (DSSCs).

Even though there are many books and reports on EIS, it is often very difficult to explain the EIS spectra of DSSCs.

Understanding EIS through calculating EIS spectra on spreadsheet can be a powerful approach as the user, without having any programming knowledge, can go through each step of calculation on a spreadsheet and get instant feedback by visualizing the calculated results or plot on the same spreadsheet.

Here, a brief account of the EIS of DSSCs is given with fundamental aspects and their spreadsheet calculation.

The review should help one to develop a basic understanding about EIS of DSSCs through interacting with spreadsheet.
