Cu2O photoelectrodes with dominant [111] orientation display substantially higher carrier mobility compared with other crystallographic orientations. Higher mobility arises from favorable band-structure features and reduced effective masses along the [111] direction, together with fewer mobility-limiting defects and grain-boundary scattering. Enhanced carrier transport increases photocurrent and improves charge separation, reducing recombination losses in photoelectrochemical cells. Orientation-controlled synthesis and epitaxial growth strategies enable fabrication of [111]-oriented Cu2O films with superior electronic properties. These improvements support more efficient solar-driven chemical conversion and photovoltaic applications using Cu2O-based photoelectrodes.
