FAQs
Q1: What is Methylammonium Lead Iodide (MAPbI₃)?
Answer: Methylammonium Lead Iodide (MAPbI₃) is a lead halide perovskite material, consisting of methylammonium (CH₃NH₃⁺), lead (Pb²⁺), and iodide (I⁻) ions. It is widely used in perovskite solar cells due to its excellent light absorption, charge transport, and high power conversion efficiency.
Q2: Why is MAPbI₃ used in solar cells?
Answer: MAPbI₃ is used in solar cells because it has an ideal band gap (~1.55 eV) for absorbing sunlight, high charge-carrier mobility, and long diffusion lengths, which contribute to high power conversion efficiencies, often exceeding 20%.
Q3: How is MAPbI₃ synthesized?
Answer: MAPbI₃ is typically synthesized using solution-based methods such as spin-coating, vapor deposition, or other scalable processes. These methods are relatively simple and cost-effective, making them suitable for large-scale manufacturing of devices.
