MACl, as additive to the standard FAPbI 3 precursor solution , enables near‐complete coverage perovskite film to stabilize the phase‐pure black FAPbI 3 annealing at 100 °C. A partial substitution of FACl for FAI in precursor solution is used to grow FA perovskites with controllable chlorine doped fraction, which improves the performance of the planar perovskite solar cell.
