Electrical and Optical Properties of CuO-Cu₂O Phase Mixture for Solar Cell Applications

CuO and Cu₂O both being direct bandgap material and having high absorption co-efficient, have potential application for fabrication of solar cell. These two materials have been separately used as an active layer in solar cell manufacturing. But using different ratios of CuO and Cu₂O phase content can bring variance in absorbance which can present new and diverse aspect in solar cell fabrication with added efficiency. This research has synthesized Cu₂O–CuO nanocomposites using a hydrothermal technique and characterized the structural, optical, and electrical properties of phase mixture of CuO and Cu₂O using X-rAY diffraction (XRD), Raman, UV-VIS, scanning electron microscopy (SEM), and 4-probe resistance measurement techniques. Also after the qualitative study of the phase mixture, this research targets to fabricate a solar cell using the CuO+Cu2O phase mixture with the optimum ratio. The result obtained from this research will be discussed in this presentation.
