Study on the Passivation of Defect States in Wide-Bandgap Perovskite Solar Cells by the Dual Addition of KSCN and KCl

Wide-bandgap (WBG) perovskite solar cells (PSCs) are critical for high-efficiency tandem photovoltaic devices, but their practical application is severely limited by phase separation and poor film quality. To address these challenges, this study proposes a dual-additive passivation strategy using po...
