Abstract
Perovskite solar cells have attracted extensive research attention recently as they are promising high-performance solar cells with long-time stability at a low cost. In this study, we demonstrated a one-step solution approach to prepare the CH3NH3PbICl2 perovskite layer by adding lead chloride (PbCl2) to the standard methylamine iodide (MAI) precursor solution and annealing process of the perovskite layer at different temperature. Finally, the Ag/Spiro-OMeTAD/CH3NH3PbI2Cl /mp-TiO2/c-TiO2/FTO/Glass perovskite solar cell was successfully fabricated by using solution processing.
