This work consists in studying solar cells whose active layer is made up small molecules: CuPc and C60 with the insertion of a nano metal layer enter the anode and the donor of electron. The aluminum doped zinc oxide ZnO:Al instead of indium tin oxide ITO is used as the anode. An ultrathin gold film is introduced among ZnO:Al, transparent conductor oxide, and the CuPc donor layer. Various analyses were carried out on this solar cell and its materials to try to understand the various processes intervening on a molecular scale during its manufacture and of its operation in order to improve its performances. Voltage measurements were taken to obtain the characteristics of the cell (current of shortcircuit, tension of open circuit, factor of filling, output). XPS studies were used to determinate of the Cu 3d and Zn 3d peak binding energies. Source
