What is the mode for measuring photocurrent of a photocatalyst?

I am attempting to measure the photocurrent of my photocatalyst using a Gamry Interface 1010E. I am not sure if it works because I will shine light once, not as pulses.

Can l use only working electrode and a counter electrode for measuring the electrochemical impedance without a refrence electrode?

I tried to measure the EIS of my photocatalyst by using only a working electrode (my catalyst was dip dropped on FTO) and a counter electrode (Pt), but most of the times it showed a high impedance...

Can the colour of Cu2O be a yellowish red instead of brick-red?

I have synthesized Cu2O several times. One time l recognized that the colour of it was yellowish red. I thought the reason because l didn't controled the temperature well. But today when l tried...

Can I use ferrocene as a reference electrode for measuring the EIS of a photocatalyst?

Actually, I want to use ferrocene as a refence electrode to measure the EIS of perovskite catalyst. and should I follow the same steps as that electrochemical cell contains Ag/AgCl as a reference...
