Abstract:The performance of conventional methylammonium (MA)‐based perovskite solar cells (PSCs) and their MA‐free counterparts showcase explicit divergence in device performance often stemming from crucial open‐circuit voltage (VOC) deficits while employing NiOx hole‐transport layer (HTL). In this work, the performance of MAPbI3 and FA0.9Cs0.1PbI3 based PSCs are correlatively analyzed using surface photovoltage (SPV) and photocurrent density (Jph) studies for the first time to quantify hole selectivity and contact pas… Show more
