Solar cells fabricated by Organic−inorganic perovskite material because of optimal properties including direct band gap, large absorption coefficients, high carrier mobility and easier process is under consideration by the researcher, recently. One of these promising organic-inorganic material is CH3NH3PbI3 which prepare by mixture of PbI₂ and CH3NH3I. In this research, PbI₂ powder was synthesized with Golderin technique and by two different calcination procedures and used in preparing perovskite material. Then, the perovskite solar cells with planar structure were fabricated using these materials and also PbI₂ powder purchased from Sharif Solar Company as a reference. Then, the solar cell performance including photovoltaic performance and cell efficiencies were compared. Results indicate that the solar cell samples in which PbI₂ prepared with heat-shock -process have better photovoltaic performance such as short circuit current density, fill factor and efficiency. It should be noted that these reported data are related to hole-transport- free perovskite solar cells.
