On the other hand, considering the process on the other electrode, the excited electrons can be transferred from the conduction band to the cathode, thus decreasing the overall current. In the low voltage regime, the competing process on the anode is favorable because of the potential on the mat, resulting in a slight increase in current. Whereas photocurrent switching is common and was observed in electrochemical setups, it is uncommon in solid-state type devices and requires a complex field-effect transistor configuration.
