CONSIDRERATION ON SOME PROBLEMS OF ANALYSIS BY ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY

摘要

Electrochemical impedance spectroscopy (EIS) is known asnone of the excellent methods to obtain information concerning thenelectron transport processes in dye-sensitized solar cells (DSSCs).15nThe EIS, in particular, can determine many parameters involved innthe electron transport processes in DSSCs simultaneously under thenvery conditions applied to the cell in operation.5,6 However, therenare some problems on analysis by EIS. (1) A number of studies innthe literature analyzed the electron transport processes based on thenEIS measurements under dark conditions, while thenphotocurrentvoltage (I V) measurements were carried out undernone-sun illumination conditions.6,7
