Abstract
In this work, we report perovskite solar cells in the planar p-i-n configuration based on single-step, anti-solvent-free, low-temperature (70 °C) slot-die-coated methylammonium lead tri-iodide (MAPbI3). The devices are fabricated on hydrophobic poly(triarylamine) (PTAA) surfaces, using key strategies such as solvent engineering, enhanced ink-substrate dynamics, and surface passivation, enabling a power conversion efficiency (PCE) of 21.8%. We also adapted the technique to achieve the first slot-die-coated perovskite/silicon monolithic 2-terminal tandems, achieving a PCE of 23.8% utilizing a textured silicon bottom cell.
