Applications

FABr introduces bromide onto the halide site of formamidinium perovskites. Partial bromide substitution widens the bandgap and improves phase stability, which makes FABr a standard tool for tuning mixed-halide compositions toward tandem and wide-bandgap applications.

  • FAPbBr3 and mixed-halide FAPb(I1-xBrx)3 absorbers
  • Wide-bandgap top cells for perovskite-silicon tandems
  • Green perovskite light-emitting diodes
