In this work, efficient mixed organic cation and mixed halide (MA<sub>0.7</sub>FA<sub>0.3</sub>Pb(I<sub>0.9</sub>Br<sub>0.1</sub>)₃) perovskite solar cells are demonstrated by optimizing annealing conditions. AFM, XRD and PL measurements show that there is a better perovskite film quality for the annealing condition at 100 °C for 30 min. The corresponding device exhibits an optimized PCE of 16.76% with <i>V</i><sub>OC</sub> of 1.02 V, <i>J</i><sub>SC</sub> of 21.55 mA/cm² and FF of 76.27%. More ...[more]
