We are diong at first scan from 0V to 1 V (for n-type of semiconductor) and from 0V to -1V (for p-type semiconductor) (custom sweep in GillAcc). Scan rate 5 or 10 mV/s. We are using chopped light: 5 sec on - 5 sec off. When wee are doing this LSV scan, we measure at what potential we get the max photocurrent, and at this potential we then make chronoamperometry scan, and also we do the same scan at the potential, when photocurrent stars, also using the chopped light. Also we make the scan, where we are measuring pitential and current vs time (this program we have in potentiostat GillAS).
As Xeniya Alexandrovna Leontyeva mentioned, measuring photocurrent in photoelectrochemical experiments requires specialized techniques and setups. Your experimental setup should include a photoelectrochemical cell, a light source, an electrolyte solution, and an electrochemical workstation.
Photocurrent measurement techniques include Transient Photocurrent (TPC), Intensity Modulated Photocurrent Spectroscopy (IMPS), Intensity Modulated Photovoltage Spectroscopy (IMVS), and Impedance Spectroscopy.
By combining these techniques, you can gain a comprehensive understanding of the photocurrent behavior and the underlying photoelectrochemical processes.
I wish you the best of luck with your experiments!
