ABSTRACT

Impedance Spectroscopy (IS) has become a major tool for investigating the properties and quality of dye-sensitized solar cell (DSC) devices. This chapter provides an introduction of IS interpretation methods focusing on the analysis of DSC impedance data. It also presents a scope of the main results obtained so far. IS gives access to fundamental mechanisms of operation of solar cells, for which reason we discuss our views of basic photovoltaic principles required to realize the interpretation of the experimental results. The chapter summarizes some 10 years of experience of the authors with regard to modeling, measurement and interpretation of IS applied in DSC.
