Abstract
We report the use of a vortex fluidic device (VFD) to prepare the precursor solution for CH₃NH₃PbI₃-⨯Cl⨯ 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.
