Methylammonium Lead Iodide (MAPbI₃) is a hybrid organic-inorganic compound commonly used in perovskite solar cells. It consists of methylammonium ions, lead ions, and iodide ions, forming a crystal structure that is efficient in absorbing sunlight and converting it into electricity. This material has gained attention for its high efficiency and low production costs compared to traditional solar cell materials. However, concerns about its stability and the toxicity of lead have prompted research into safer alternatives and methods to improve its durability in real-world applications.
