Effect of the thickness of the ZnO buffer layer on the properties of electrodeposited p-Cu2O/n-ZnO/n-AZO heterojunctions

Transparent conducting Cu₂O/non-doped ZnO/Al-doped ZnO/FTO heterojunction solar cells were fabricated by a three-step electrodeposition; with non-doped ZnO film as a buffer layer between-AZO thin film and p-Cu₂O nanostructure.
