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
