Cs0.05 Fa0.98ma0.02 0.95pb I0.98br0.02 3. The ‘95:5 triple halide (th)’ perovskite precursor solution was prepared by mixing two 1.5 m fapbi3 and mapbbr3 perovskite solutions in dmf:dmso (4:1 volume ratio, v/v) as well. 在此，开发了一种 (fa 0.83 ma 0.17) 0.95 cs 0.05 pb(i 0.83 br 0.17) 3 (csfama) 钙钛矿薄膜制造技术，该技术使用溶剂挥发而无需任何抗溶剂。 这些薄膜是通过中间相.

The ‘95:5 triple halide (th)’ perovskite precursor solution was prepared by mixing two 1.5 m fapbi3 and mapbbr3 perovskite solutions in dmf:dmso (4:1 volume ratio, v/v) as well. Pb 0 is the primary defect.
