Methylammonium Chloride (MACl)
An ammonium chloride salt that never survives to the finished film, only shapes it on the way there.

Applications
MACl is the most widely used additive for FAPbI3 film growth. The volatile methylammonium and chloride leave the film during annealing, guiding intermediate-phase crystallization and enlarging grains; most high-efficiency FAPbI3 recipes include tens of mole percent MACl.
- Crystallization control and grain growth in FAPbI3 films
- Intermediate-phase engineering in sequential and one-step deposition
- Stabilizing the photoactive alpha phase of FAPbI3
