Abstract
The simple hot-water-vapor (HWV) method was used to make the copper oxide nanostructures on Cu sheets for this study. The effects of oxidation times of 8, 16, and 24 h were investigated for use in solar cells. The samples were characterized using FESEM, EDX, XRD, Raman, and DRS measurements. It is found that with increasing the synthesis time duration: (1) the FESEM images showed a combination of cubic and nano-leaves gradually turned into compact nano-leaves; (2) EDX, XRD, and Raman analyses on the samples showed that the layers that were grown got closer to the CuO phase’s elemental ratio, and the crystallite size (D) grew from 17.55 to 34.66 nm; (3) It was found that the CuO phase-related band gap decreased from 1.62 to 1.43 eV as the crystallinity and phase purity of the samples improved, which could be a beneficial property for solar cell applications.
