采用电化学沉积法在热氧化的p型掺钠Cu_2O（p-Cu_2 O：Na）片上外延生长掺锰Cu_2O（Cu_2O：Mn）薄膜，形成Cu_2O同质结。通过在Al掺杂ZnO（AZO）透明电极和p-Cu_2 O：Na片之间插入Cu_2 O：Mn薄膜制备的太阳能电池的光伏性能得到显著改善。AZO/Cu_2O：Mn/p-Cu_2 O：1 ~ n太阳能电池的光伏性能可以通过改变Cu_2 O：Mn薄膜中Mn的掺杂量来控制。采用i型半导体Cu_2O：Mn薄膜制成的AZO/Cu_2O：Mn/p-Cu_2 O：Na太阳能电池的效率为4.21%。
The Cu_2O homojunction was formed by epitaxially growing a manganese-doped Cu_2O (Cu_2O:Mn) thin film on thermally oxidized polycrystal-line p-type sodium-doped Cu_2O (p-Cu_2O:Na) sheets by electrochemical deposition. A significant improvement of photovoltaic properties was achieved in solar cells fabricated by inserting a Cu_2O:Mn thin film between an Al-doped ZnO (AZO) transparent electrode and p-Cu_2O:Na sheets. The photovoltaic properties obtained in AZO/Cu_2O:Mn/p-Cu_2O:l« solar cells were controlled by changing the Mn content doped into the Cu_2O:Mn thin film. An efficiency of 4.21% was obtained in an AZO/Cu_2O:Mn/p-Cu_2O:Na solar cell fabricated with a Cu_2O:Mn thin film that was identified as an i-type semiconductor.
