Influence of Parameters of Cold Isostatic Pressing on TiO₂ Films for Flexible Dye-Sensitized Solar Cells

Figure 5

Nyquist impedance results of DSCs after various CIP processes. (a) Schematic diagram of the –Im(Z) versus Re(Z) curve; (b) Nyquist impedance results of samples without CIP and with CIP at different pressures for 300 s; (c) Nyquist impedance results of samples with the same CIP pressure of 200 MPa but different holding time; (d) calculated overall internal resistance of TiO₂ films after various CIP pressing. The overall internal resistance of the sample without pressing is 55 ohm.
