Equivalent circuit based on EIS and current-voltage characteristics of DSCs. was attributed to the resistance of a diode. The sum of (Warburg impedance), and corresponds closely to the series resistance of DSCs. A constant-current source is in parallel with . and are capacitance elements.
Dependence of of DSCs on RF of Pt counterelectrode.
Dependence of of DSCs on thickness of electrolyte layer.
Dependence of of DSCs on sheet resistance of TCO.
Current-voltage characteristics of DSC sensitized with the black dye. The results were obtained at Research Center for Photovoltaics, AIST, and measured at 25 °C with an aperture area of using a metal mask, irradiance of , and scan mode from to . , , , fill factor , , , , and the efficiency . The solid line and dashed line indicate current and power, respectively.
