Abstract

Abstract: Abstract : The Cu2 O homojunction was formed by epitaxially growing a manganese-doped Cu2 O (Cu2 O:Mn) thin film on thermally oxidized polycrystalline p-type sodium-doped Cu2 O (p-Cu2 O:Na) sheets by electrochemical deposition. A significant improvement of photovoltaic properties was achieved in solar cells fabricated by inserting a Cu2 O:Mn thin film between an Al-doped ZnO (AZO) transparent electrode and p-Cu2 O:Na sheets. The photovoltaic properties obtained in AZO/Cu2 O:Mn/p-Cu2 O:Na solar cells were controlled by changing the Mn content doped into the Cu2 O:Mn thin film. An efficiency of 4.21% was obtained in an AZO/Cu2 O:Mn/p-Cu2 O:Na solar cell fabricated with a Cu2 O:Mn thin film that was identified as an i-type semiconductor.
