• Description: Methylammonium bromide (MABr) is a precursor for the synthesis of organic-inorganic hybrid perovskites for use in FETs, LEDs and PVs.
• Uses: Methylammonium bromide (MABr) can be used as a precursor in the preparation of methylammonium lead bromide based perovskite material with good optical properties, which include green emission, and photoluminescence. This material can further be utilized in the fabrication of renewable energy devices such as light emitting diodes(LEDs), perovskite solar cells (PSCs), and photovoltaic cells.
