Investigation of the Optical and Electrical Properties of ITO/ZnO/CdS/CuO:Co/Ag Structure for Solar Cell

Figure 1

Transmission spectra of the ZnO, CdS, and CuO:Co thin films as a function of the wavelength. The inset shows the band diagrams of the isolated states of the ITO/ZnO/CdS/CuO:Co/Ag heterojunction under the equilibrium condition.
