is significantly higher than the control device (Rrec = 6.18 kΩ), suggesting that the RbAC additive could minimize carrier recombination, thereby increasing theVoc of the PSCs51,52. Additionally, the reduction of dark current density by RbAC additive was evidenced by darkJ-Vmeasurements (...
The hysteretic phenomenon commonly exists in the J–V curves of perovskite solar cells with different structures, especially for carbon-based mesoscopic perovskite solar cells without hole-conductor (carbon-based PSCs). By adding moderate amounts of methylammonium chloride (MACl) into MAPbI3 perovskit...
