Abstract The photovoltaic behavior in a design of SnO2/Pb2CrO5 thin film/metal (Au or Al) is described as functions of light intensity and wavelength for two different illumination directions. The Pb2CrO5 thin film in each device is formed over the SnO2 coated glass substrate by an electron-beam evaporation technique. When illuminated from the metal side, the device with Au or Al shows the positive or the negative photovoltage, respectively. For the illumination from the SnO2 side, the device with Au has the negative photovoltage at the short wavelength, and the positive one at the longer, while the device with Al has the negative photovoltage at both wavelength regions. These photovoltaic devices have two junctions at both sides of the Pb2CrO5 thin film. The band model of each device is also discussed.
