Fig. 5From: Fabrication of Semiconducting Methylammonium Lead Halide Perovskite Particles by Spray TechnologySchematic of the proposed method for the preparation of micrometer-sized and nanometer-sized perovskite particles in a suggested two-stage heater. The first stage is for rapid solvent evaporation (~ 275 °C), whereas the second stage (~ 175 °C) is for complete drying and in situ annealingBack to article page
