In this work, perovskite solar cells were fabricated with one-step method by using spin coating technique. These solar cells were in the structure form of FTO/compactTiO 2 /mesoporousTiO 2 /CH 3 NH 3 PbI 3 /Au. Different annealing temperatures were applied to investigate the effect of the annealing temperature on the properties of the fabricated solar cells since it lead to affect the crystallization degree of the CH 3 NH 3 PbI 3 layer. Three temperatures were used for annealing the perovskite layer typically: 60°C, 80°C and 100°C and the best result found at 100 °C where the efficiency was 5.68%, FF = 0.55, J sc = 12.637 mA/cm 2 and V oc = 0.817 V.
