Preparation (PMMA/PVA)-copper oxide nanocomposites solar cel

Abstract

Thin films have been prepared by casting techniques by blending the same ratio of polymethyl methacrylate (PMMA) and polyvinyl alcohol (PVA) with (0, 0.3, 0.6) % of copper oxide nanoparticles concentrations to production polymer nanocomposite solar cell. Structural properties have been measured by X-ray diffractions (XRD). Copper oxide nanoparticles results showed a five peaks which corresponding to crystalline structures: (110), (002), (202), (111), and (020). Infrared spectrum (FTIR) indicated that the Van der Waals force between polymer and copper oxide nanoparticles. A Field Emission-Scanning Electron Microscope (FE-SEM) have been used to study the morphology of thin film's surfaces and the particle size within the range (40-70)nm. The polymer nanocomposite solar cell photovoltaic properties included a short circuit current and open-circuit voltage (ISC-VOC), besides, that the quantum efficiency equal to 4.6 %.
