Methylammonium lead bromide, CH3NH3PbBr3 (MAPbBr3)

Methylammonium lead bromide (CH3NH3PbBr3) is a hybrid organic-inorganic perovskite material noted for its outstanding optical properties and high efficiency in photovoltaic applications. This compound forms a crystalline structure that is effective in light absorption and electron-hole separation, making it highly advantageous for use in solar cells. Its refractive index and other optical characteristics are of particular interest for optical applications, including photovoltaic devices and light-emitting diodes (LEDs).

While CH3NH3PbBr3 shows great promise in advanced technological applications, it poses environmental and health risks due to its lead content. Additionally, its stability under environmental conditions remains a subject of extensive research, aiming to enhance its durability and safety for commercial use.
