Influence of Parameters of Cold Isostatic Pressing on TiO2 Films for Flexible Dye-Sensitized Solar Cells
Figure 6
Equal circuit of DSC. R ct is the charge-transfer resistance of the charge recombination process between electrons in the TiO2 film and in the electrolyte; Rt is the transport resistance of electrons in TiO2 films; R ITO is the charge-transfer resistance at exposed ITO/electrolyte interface; Rco is the contact resistance of ITO/TiO2 interface; R pt is the charge-transfer resistance of exposed Pt/electrolyte interface; C ct, C ITO, C co, and C pt are the chemical capacitance of the TiO2 film, corresponding double-layer capacitance at the exposed ITO/electrolyte interface, capacitance at ITO/TiO2 interface, and capacitor of Pt/electrolyte interface, respectively. Rs consists of the substrate resistance and series resistance between substrate and wires [11, 12].
