Flexible perovskite solar cells (F-PSCs) hold great potential for lightweight photovoltaic applications due to their flexibility, bending compatibility, and low manufacturing cost. However, tin oxide (SnO2), as a common electron transport layer (ETL) used in F-PSCs, typically suffers from high-density surface defects that hinder the charge extraction efficiency deteriorate crystallization quality of upper film. Additionally, poor buried interface intensifies lattice extrusion strain residue across films, further aggravating mechanical brittleness devices. To address issues, we developed molecular bridging strategy by introducing 2,2′-oxybis(ethylenediamine) dihydrochloride (DO) at perovskite/SnO2 interface. The diammonium groups spacer ligands can achieve bidentate anchoring on SnO2 cooperating with oxygen atom alkyl chain passivate charged tailored properties also endow optimized films significantly alleviate tensile strengthen perovskite’s pliability. As result, F-PSCs achieved champion 23.50%, outperforming value 21.87% control device. Furthermore, devices exhibited excellent robustness, maintaining 90% initial PCE after 6000 cycles radius 4 mm. This work presents reliable synergistic optimization contact interface, contributing development efficient stable F-PSCs.
