Fabrication and Characterization of CuO-based Solar Cells

Abstract

Cuprous oxide (CuO)-based solar cells with fullerene (C60) were fabricated on indium tin oxide (ITO) by a spin-coating method. The microstructure and cell performance of the solar cells with the CuO/C60 structure was investigated. A photovoltaic device based on an ITO/CuO/C60 hererojunction structure fabricated by the spin-coating method provided short-circuit current density of 0.18 mAcm-2 and open circuit voltage of 0.04 V under illumination. The crystal structure of the CuO active layer was examined by using X-ray diffraction. The energy levels of the present solar cells are also discussed.
