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
