Using ZnO seed layers, an efficient approach for enhancing the heterointerface quality of electrodeposited ZnO–Cu2O solar cells is devised. We introduce a sputtered layer followed by sequential electrodeposition and Cu2O films. The employed to control growth crystallinity augment surface area films, thereby tuning heterointerface. Additionally, also assists in forming high with no pin-holes, pH electrolyte solution. X-ray electron diffraction patterns, scanning atomic force microscopy images, as well photovoltaic measurements, clearly demonstrate that incorporation certain layers results alteration quality, change heterojunction films near junction, which influence current density devices.
