Cu2O-ZnO nanowire solar cells are synthesized by electrodeposition from solutions near room temperature. A high-quality, self-assembling, nanostructured heterojunction is produced, which is Found to dramatically improve the charge collection efficiency in these ultra-low-cost devices. Incident-photon-to-electron conversion efficiencies approaching unity are measured and considerable efficiency improvements are observed.
