In this study, we synthesize methylammonium lead halide and discuss different fabrication temperature. The film quality of the perovskite absorber layer is evaluated by X-ray diffraction (XRD) , scanning electron microscopy (SEM) and AFM. The scattering peak at 2θ = 14.10 was assigned to the (110) plane of CH₃NH₃PbI₃ perovskite structure. We have succeeded in directly obtaining a perovskite crystal without performing an annealing treatment.
