【 摘 要 】

In this work, CdO1-x ZnOx with (x= 5and 25%) have been deposited on glass and Si substrates by chemical spray method, thin films were examined by x-ray diffractometer (XRD) which showed the films are polycrystalline also the attendance of the CdO cubic shaped and hexagonal Zinc oxide (ZnO) phases at x concentration 5% and 25% . The grain size decrease with expansion of ZnO content. The surface morphology of the samples showed densely packed grains. Optical absorption shows the effect of ZnO doping on band gap of CdO where the optical Absorption varies from 33% to 70% and the band gap various from 2.74 to 3.14 eV. Under 30mW/cm2 intensity illumination photovoltaic properties were examined. An open Circuit voltage (Voc) increase and a fill factor (F.F.) increase with increase of x concentration . The reversed bias capacity was calculate like a versus to reverse bias voltage at frequency 1 MHz. It also indicates that heterojunction was abrupt. The built in voltage increase with the increasing of x content.
