Methylamniu bromide CAS#6876-37-5
Key Precursor for Perovskite Materials: Methylammonium Bromide (MABr) is an important precursor for synthesizing organic-inorganic hybrid perovskites, including MAPbBr₃, which are widely applied in advanced optoelectronic devices.
Excellent Optoelectronic Performance: MAPbBr₃ perovskites offer a suitable band gap of 2.3 eV and can effectively tune the optical properties of mixed halide perovskite systems for enhanced device performance.
High Potential in Solar Cell Applications: MABr-derived MAPbBr₃ perovskites provide higher open-circuit voltage compared with iodide-based counterparts and have demonstrated promising photovoltaic performance in perovskite solar cells.
Outstanding Light-Emitting Properties: MAPbBr₃ nanoplatelets exhibit strong photoluminescence, narrow emission bandwidth, and high quantum yield, making them suitable for applications in LED and other optoelectronic technologies.
Product Description of Methylammonium Bromide CAS#6876-37-5
Methylammonium bromide (MABr) is an important precursor used for the synthesis of organic-inorganic hybrid perovskite materials applied in FETs, LEDs, and photovoltaic (PV) devices. It serves as a key precursor for the preparation of MAPbBr₃ perovskites.
MAPbBr₃ perovskites possess a band gap of 2.3 eV (HOMO: 5.68 eV, LUMO: 3.38 eV) and are widely used to adjust the band gap of mixed MAPbX₃ perovskites, where X represents halide combinations such as I, Br, and/or Cl. Due to their optical properties, bromide-based MAPbBr₃ perovskites can function as light absorbers for high-energy photons and can be used as front cells in tandem solar cell architectures.
Compared with iodide-based analogues, MAPbBr₃ perovskites can provide higher open-circuit voltage in perovskite solar cells. High-performance solar cells based on pure MAPbBr₃ perovskites have achieved a VOC of up to 1.40 V, a fill factor (FF) of 79%, and a power conversion efficiency (PCE) of 6.7%.
In addition, MAPbBr₃ nanoplatelets have demonstrated potential for LED applications, showing strong photoluminescence (PL) emission at 529 nm, a narrow emission spectrum, and a quantum yield of up to 85%.
