Hello ,

I'm trying to take external quantum efficiency measurements. I'm measuring the p-type photocathode thin film in a NaCl liquid in a three-electrode system (pt, Ag/AgCl and working electrode). but I think the measurements are not giving correct results. Since the results of all the different samples I took were the same, I took the measurement in its cavity. all results are the same. I checked the electrodes and they are fine. There is no problem with the machine. I think I made the wrong connect. I would appreciate if you share the correct connect with me.

Thanks for your help .
