In first step, PbI2 solution deposited on TiO2 nanostructure by spin coating method. Then the substrate dipped in Formamidine iodide solution at different temperatures to form HC(NH2)2PbI3 perovskite. The photovoltaic characterization of solar cell such as the power conversion efficiency (PCE), Fill Factor (FF), Open Circuit Voltage (Voc) and Short Circuit Current (Jsc) were analyzed to obtain the optimum dip-coating temperature.
