Synergistic molecular mixing of FAPbI 3 and CsSnI 3 perovskites (FA=formamidinium) and formation of new crystalline alloy perovskites are reported by X. W. Sun, Y. Zhou, N. P. Padture, et al. in their Communication on page 12658 ff. The alloy perovskite of the composition (FAPbI 3 ) 0.7 (CsSnI 3 ) 0.4 has an anomalous ideal bandgap of 1.3 eV for single‐junction thin‐film solar cells with an unusually high photocurrent.
