The orbital overlap of the carboxyl oxygen with the Sn atom alongwith the homogenous nano\u2010particle deposition effectively suppresses the interfacial defects and releases the internal residual strains in the perovskite. Accordingly, a PCE of 24.91\u2009% with a fill factor (FF) up to 0.852 is obtained for in situ passivated devices, which is one of the highest values for SnO\n                    <jats:sub>2<\/jats:sub>\n                    \u2010based PSCs.
