Chemical structure of methylammonium bromide (MABr), CAS No. 6876-37-5


Methylammonium bromide (MABr) is a precursor of MAPbBr3 perovskites. Having a band gap of 2.3 eV (HOMO 5.68 eV, LUMO 3.38 eV) [1], MAPbBr3 perovskites have been used to tune the band gap of mixed MAPbX3 (where X is the halide I, Br and/or Cl mixtures) [2,3,4,5,6]. For this reason, bromide MAPbBr3 perovskites can be utilised as light absorbers for high-energy photons, and can serve as the front cell in tandem cells. This perovskite can provide a higher open-circuit voltage in perovskite solar cells than the iodide analogue.

High-efficiency solar cells, with a VOC of up to 1.40 V, a fill factor (FF) of 79%, and a PCE of 6.7% have been reported for pure MAPbBr3 perovskite solar cells [1].

It has also been demonstrated that MAPbBr3 nanoplatelets can be employed in light-emitting diodes, exhibiting bright photoluminescence (PL) at 529 nm, with a narrow spectral band and a quantum yield up to 85% [7].

How to Make Efficient Perovskite Solar Cells in a Glove Box

Various other perovksites and transport materials, along with references and examples of their uses, can be found on our "Ultimate Guide to Perovskites" page - but we thought it would be useful to demonstrate an example of how to make a PSC (that can acheive over 19% PCE), from start to finish. We've also tried to include some helpful tips to perfect your technique.
