Application

Methanamine hydriodide is an important precursor for the preparation of perovskite photoactive layers for solar energy conversion.
Methylammonium iodide (MAI) is extensively used as a precursor material for the fabrication of perovskite solar cells. These solar cells offer high conversion efficiencies.
Methylammonium iodide can be used as a precursor in combination with lead iodide to change the morphology of the resulting perovskite materials. Perovskite materials can further be utilized in the fabrication of alternative energy devices such as light emitting diodes (LEDs), and perovskite solar cells (PSCs).
