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.
Hi, to do this, begin by setting up the electrochemical cell with the working electrode coated with your photocatalyst, a reference electrode, and a counter electrode. Calibrate the electrodes using a standard solution for accurate measurements. Record the dark current as a baseline before exposing the working electrode to continuous light. Ensure that the light source covers the relevant wavelength range for your photocatalyst. Allow sufficient time for the system to reach steady-state conditions under light exposure and then record the photocurrent generated. Since you're using continuous light and not pulses, maintain a stable light intensity throughout the measurement. Verify that the wavelength of the light source matches the absorption spectrum of your photocatalyst. Control the light intensity if possible, and analyze the obtained photocurrent data.
