Figure 5. The predicted phase diagrams of mixed halide perovskites [APb(I1-xBrx)3], A = (A) FA0.75Cs0.25; (B) FA0.5Cs0.5; (C) FA0.25Cs0.75; (D) MA0.75Cs0.25; (E) MA0.5Cs0.5; (F) MA0.25Cs0.75; (G) FA0.75MA0.25; (H) FA0.5MA0.5; (I) FA0.25MA0.75. The binodal and spinodal lines and regions are shown in blue and red, respectively. The light intensities are illustrated by greyscale shaded areas (~2-sun, 10-sun).
