摘要	Dye-sensitized solar cells (DSC) are regarded as a potential low-cost alternative to conventional solar cells and have attracted considerable interest during the past decades. The working mechanism of DSC is not yet fully been understood and needs further investigation. Electrochemical impedance spectroscopy (EIS) is a powerful technique to identify and study the working mechanism in DSC. Through the EIS measurements, some parameters, such as electron transfer resistance, electron transport resistance, capacitance, ion diffusion resistance, electron diffusion constant and electron lifetime, etc. can be obtained. After further processing of these data, the charge transport kinetics, the electron transfer kinetics, the electron collection kinetics, the semiconductor energy level changes and the density of states distribution can be analyzed. This paper summarizes the basic theory and experimental methods of EIS application in DSC. The latest research progress about the charge transport process, the electron transfer process, the impedance of DSC information extraction and the dynamic process analysis are reviewed. Furthermore, the application of EIS in various research fields of DSC, such as photoanode, electrolyte system, counter electrode, stability test, new structure design are introduced. Especially, the impedance characteristics of the various components of DSC are summed up and the latest progress in the study of the work mechanism in DSC are systematically summarized. The current problems existed in the research of EIS application for DSC are discussed and the future development is prospected.
