The chief aim of this study was to prepare air-stable hybrid perovskite thin film materials incorporating earth abundant and non-toxic transition metals which include Ni, Cu & Zn (doped at 1, 5 and 10%); CH3NH3PbI3•Ni, CH3NH3PbI3•Cu & CH3NH3PbI3•Zn, employing a two-step solution deposition technique. The terephthalic acid (TPA) additive was utilized to stabilize thin film materials from deterioration upon exposure to air.enDislocation densityEco-toxicityGrain boundariesPower conversion efficiencyNanomaterialsUniversity of Western Cape
