We report the use of a vortex fluidic device (VFD) to prepare the precursor solution for CH 3 NH 3 PbI 3‐x Cl x perovskite films. These films exhibited improved surface coverage and enhanced light absorption relative to conventional batch processing used for preparing the precursor solution. This VFD‐assisted perovskite solar cell displayed a power conversion efficiency of 11.65 %, which is significantly higher than 9.26 % of the control device.
