Capillarity‐Assisted Electrostatic Assembly of Hierarchically Functional 3D Graphene: TiO₂ Hybrid Photoanodes

Rational engineering of electrostatic and capillarity-induced mechanical cues transforms stimuli-responsive rGO sheets into nanotextured, mechanically durable, electrically conductive binders for TiO2-based photoanodes. The resulting device exhibits a substantially enhanced Jsc, largely preserved FF, and excellent retention under iterative mechanical bending cycles.
