Abstract The triiodide lead methylammonium MAPbI3 perovskite solar cells have attracted big attention especially when they were manufactured with different precursors mainly that based on lead chloride. In this report, the effects of the incorporation of PbCl2 into precursor solutions of the perovskite MAPbI3 on the microstructures, optical and photovoltaic properties were examined. The perovskite solar cells elaborated with the MAPbI3-xClx perovskite films treated by the optimal concentration of (MAI: PbCl2) has showed a preferred crystalline orientation and an improvement of the performances. Furthermore, the effect of different solvent volumes of (DMF: DMSO) on photovoltaic performance was investigated. The highest performance was obtained for the cell made from precursor solution dissolved in DMF resulting from the good interaction of the materials with the perovskite material.
