Abstract: Two types of ordered InP nanowire arrays have been prepared on the same anodic aluminum oxide template by a template-assisted metallo-organic chemical vapor deposition technique. When using template with an appropriate pore size, free-standing wires on the template surface and highly ordered wires in the nanochannels of the same template can be simultaneously achieved. The highly ordered InP nanowire arrays in the nanochannels serve as an n-type semiconductor to assemble the p-n heterojunction solar cell with p-type Cu2O. Such a Cu2O/InP p-n heterojunction solar cell possesses a power conversion efficiency of 1.55%.
