One of the most promising contenders in the race for efficient, cost-effective solar materials is the perovskite solar cell. The solar-cell devices in this work consist of an etched glass substrate coated with indium tin oxide, a nickel oxide layer, a hybrid organic-inorganic perovskite layer, a zinc oxide layer, and a metal electrode layer. The (CH3NH3)PbI3 perovskite is the optically active layer, akin to the electron-donor material in heterojunction solar cells, absorbing light and injecting electrons (and holes) into conducting media. The addition of Al to the n-type ZnO layer can increase both conductivity and optical transmission. Therefore, this research seeks to produce functional lead-halide perovskite solar cells and observe the changes in electrical conductivity and energy conversion efficiency when the zinc oxide layer is doped with aluminum. All layers were fabricated using solution processing methods.
