In this paper, the researchers fabricated MAPI perovskites using slot-die coating with KSCN additive, and a modified solvent mixture. These modifications lead to higher performance (avg PCE 20.14%, all key figures improved), lower hysteresis, and a longer device lifetime. The researchers used the characterization tool Paios to increase TPV lifetime, larger recombination resistance from IS and shorter TPC decay times for KSCN modified cells to support better charge transport properties and lower defect densities.
