XRD pattern of perovskite powder prepared by a anti-solvent method, b milling method at two PbI2/MAI mass ratios, and c spray method when the temperature of the second heater (second stage of heating) is kept at two different temperatures of 175 and 275 °C, while the first heater (first stage of heating) is kept at 275 °C in both cases. The asterisk denotes the perovskite peaks
