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.en© 2017 Wiley-VCH Verlag GmbH & Co.
