Gold, silver and nickel used as electrodes in the fabrication of perovskite solar cell by using thermal evaporation deposition method with direct structure FTO\ TiO 2 \ MAPbI 3 \ spiro-MeOTAD\ metal electrode. The cell efficiency was compared between the electrodes material as a function of time to explaining the effect of these metals electrode on cell performance, X-ray diffraction pattern showed that the samples that contain gold and nickel do not contain a compound indicating the interaction of the metal with the components of the cell or the formation of a new compound, while in the cell containing silver it was found that silver iodide is formed after the passage of time. Under standard AM1.5 illumination, the device shows a power conversion efficiency of 4.42%, 3.50%, and 1.61% for Au, Ni and Ag electrodes respectively. Devices with Au and Ni give same behaviours where reduce efficiency after 7day to 20% but for Ag reduce efficiency to 80%. The results revealed that, Nickel can become the best choice as an electrode for the perovskite solar cell in terms of price and efficiency approach to gold.
