We have synthesized certain electrode material for DSSC application and coated electrodes material on FTO. We have connected one electrode with counter and reference electrode assembly and the other one with working and sensing electrode assembly. The electrolyte has been immersed between both electrodes. However, we are not getting proper Nyquist plot as well as bode plots, as you can see there is no phase change with varying frequency.
Dear Dr. Nisar Ahmed
That depends upon the used materials. some mixed metal oxide have the same property. You need to add the nyquist plot to illustrate the diagnosis
Dear Nisar Ahmed ,
if possible, then show, please, a schematic drawing (or a photo) with the 4-(ohmic?) contacts (on the layers) of your device.
Some notes about the EIS-measurements:
1) measure down to 10mHz,
2) apply some VDC polarization parametric values, say two values, -2V , +2V.
3) Apart, a)dark-EIS, measure-EIS, b)under (some available) illumination, also.
Dear Dr. Ioannis Samara,
Thank you so much for your valuable comment. We have sort out the issue, it was arising due to evaporation and early consumption of electrolytes. We immersed the electrodes inside the beaker filled with electrolyte, instead of immersing the electrolyte inside the electrodes.
