General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for "Energy efficiency".

Application

Methylammonium bromide (MABr) is used as an additive in the fabrication of perovskite solar cells. It helps improve the crystal quality and stability of the perovskite films, leading to enhanced photovoltaic performance.
Organohalide based perovskites have emerged as an important class of material for solar cell applications. Our perovskites precursors with extremely low water contents are useful for synthesizing mixed cation or anion perovskites needed for the optimization of the band gap, carrier diffusion length and power conversion efficiency of perovskites based solar cells.

Caution

  • Extremely hygroscopic.
  • Handle in glove box.
  • Handle and store under nitrogen atmosphere.
