摘要: Abstract A new transfer function based on capacitance measurements via an intermodulation technique is introduced for characterizing dye-sensitized solar cells (DSSC). two-frequency composite signal applied measuring the frequency dependence of first derivative with respect to potential a relevant electrochemical system under test. In case DSSC, probed corresponds that SnO2–TiO2 rear contact. Using general formalism initially developped any interface, explicit expressions have been derived DSSC and quantitatively compared experiments. Information electron dynamics similar provided by IMPS, but in addition allows TiO2 nanostructure contact surface area be readily determined.
