The photovoltage due to the photocarrier injections (PCI) effect at the heterojunction of YBCO/STO:Nb was investigated using x-ray photoemission spectroscopy (XPS) combined with the laser source. The magnitude of the photovoltaic-induced shift in the core level was found to be 0.78 V at a laser frequency of 30 Hz at 130 K. The relaxation time of the photovoltage and maximum photovoltage was also analyzed. It was concluded that the photovoltage can be slightly enhanced with cooling from 300 to 130 K and saturated below 130 K.
