Effects of Annealing Conditions on Mixed Lead Halide Perovskite Solar Cells and Their Thermal Stability Investigation.

ABSTRACT: In this work, efficient mixed organic cation and mixed halide (MA_0.7FA_0.3Pb(I_0.9Br_0.1)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 V_OC of 1.02 V, J_SC of 21.55 mA/cm² and FF of 76.27%. More importantly, the mixed lead halide perovskite MA_0.7FA_0.3Pb(I_0.9Br_0.1)₃ can significantly increase the thermal stability of perovskite film. After being heated at 80 °C for 24 h, the PCE of the MA_0.7FA_0.3Pb(I_0.9Br_0.1
