N2 - A simple approach is introduced to prepare high crystallinity CH3NH 3PbI3 perovskite films with larger crystalline grains and longer carriers lifetime by using magnetic field to control the nucleation and crystal growth. The fabricated planar PSCs have an average PCE of 17.84% and the highest PCE of 18.56% using optimized magnetic field at 80 mT. In contrast, the perovskite solar cells fabricated without the magnetic field give an average PCE of 15.52% and the highest PCE of 16.72%. The magnetic field action produces an ordered arrangement of the perovskite ions, improving the crystallinity of the perovskite films and resulting in higher PCE.
