Perovskite solar cells have attracted widespread attention due to their high efficiency and relatively low production costs. However, optimization of the perovskite layer deposition process is very important to improve the power conversion efficiency (PCE) and stability of perovskite solar cells. Factors that can affect the performance of perovskite solar cells, namely annealing temperature and annealing time. The optimal annealing temperature increases crystallinity and reduces defects in the perovskite structure so that it can increase the short-circuit current density (Jsc) and open-circuit voltage (Voc). The optimal annealing time results in a better recrystallization process so that it can improve the crystal structure. The configuration of the perovskite solar cell sample is ITO/TiO2/CH3NH3PbI3-xBrx/Spiro-OMeTAD/Ag with spin coating and screen printing methods. The spin coating of the perovskite layer is carried out at a speed of 4000 rpm for 30 seconds. This study was conducted with variations in the second stage annealing temperature of 80°C, 100°C, and 120°C and variations in the second stage annealing time of 10 minutes, 20 minutes, and 30 minutes. The characterization carried out in this study used x-ray diffraction (XRD), scanning electron microscopy (SEM), UV-Vis spectroscopy and solar cell I-V test system. Based on the characterization of the solar cell I-V test system, the highest PCE value was 2.5933% at an annealing temperature of 120°C for 30 minutes. The right combination of annealing temperature and annealing time is very important to produce optimal PCE in perovskite solar cells. Keywords: Perovskite Solar Cell, Annealing, PCE.
