摘要：

Internal resistance in a dye-sensitized solar cell (DSC) was investigated using electrochemical impedance spectroscopy measurements. Four resistance. elements were observed in the impedance spectra, and-their dependencies on the applied bias voltage were characterized. It is found that the resistance element related to charge transport at the Tio(2)/dye/electrolyte interface displays behavior like that of a diode, and the series resistance elements largely correspond to the sum of the other resistance elements. An equivalent circuit for DSCs is proposed based on these results. (C) 2004 American Institute of Physics.
