FABRICATION AND EVALUATION OF CuO/ZnO HETEROSTRUCTURES FOR PHOTOELECTRIC CONVERSION

Abstract

Cuprous oxide (CuO)-based solar cells with zinc oxide (ZnO) were fabricated on indium tin oxide by an electrodeposition. Microstructure and cell performance of the solar cells with ITO/CuO/ZnO or ITO/ZnO/CuO structures were investigated. Photovoltaic devices based on the CuO/ZnO or ZnO/CuO heterojunction structures provided photovoltaic properties under illumination. Structural, morphological and absorption measurement of the CuO/ZnO heterojunction were studied by using X-ray diffraction, transmission electron microscopy and light current-voltage characteristics. The energy levels of the present solar cells were also discussed.
