Low cost Al-doped ZnO (AZO)/non-doped ZnO (ZO)/Cu2O heterojunction solar cells with a high conversion efficiency of 4.04% were fabricated by depositing transparent conducting AZO and ZO thin films on high quality Cu2O sheets prepared by thermally oxidizing copper sheets. To achieve higher efficiencies, it is necessary to form the AZO and ZO thin films at a low deposition temperature using a low-damage...
