摘要：

Changes in the composition of the electrolyte are known to affect the parameters that determine the performance of dye solar cells. This paper describes a robust method for the analysis of the photovoltage in dye solar cells. The method focuses on the study of recombination resistance and chemical capacitance of TiO2 obtained from impedance spectroscopy. Four dye solar cells with electrolytes producing known effects on photovoltage behavior have been studied. Effects of conduction band shifts and changes in recombination rate in the photovoltage have been evaluated quantitatively.
