We study the properties of the series of compounds Cs<sub>0.15</sub>FA<sub>0.85</sub>Pb(Br<sub>x</sub>I<sub>1−x</sub>)3, aiming to develop an efficient complementary absorber for MAPbI<sub>3</sub> in all-perovskite tandems. A bromide content of 0.7 leads to a band gap of 2 eV and a maximum PCE of 11.5% in solar cells, among the highest reported for band gaps wider than 1.8 eV.
