Abstract

The differences in charge separation and transfer processes between the ‘non-charge-separation’ terminal surface and perovskite/FTO ‘charge-separation’ interface have been studied using comparative lock-in amplifier-based SPV signals. The SPV phase vector model delves deeper into the direction of charge separation and trapping at the perovskite surface/interface.
