PHOTOVOLTAIC PRODUCTION TECHNOLOGIES AND ASSESSMENT OF SOLAR CELL EFFICIENCIES FOR NANOSTRUCTURED COBALT DOPED ZINC OXIDES
Öz
In this study, the synthesis and characterization of cobalt doped zinc oxide (Co:ZnO) nanocomposite materials were achieved using hydrothermal method from zinc nitrate and Cobalt (II) chloride precursors. Zinc oxide nanostructures were doped with cobalt in different dopant concentrations. The Co concentration was varied from 0.5 to 1.5 mol % in ZnO crystalline structure. Cobalt doped ZnO materials were analysed using XRD, SEM and EDX. Also DSSC performances of cobalt doped ZnOs were studied. Best efficiency was obtained with 1% doped Co:ZnO as 3.48 mA/cm2 of short circuit photocurrent density, 600 mV of open circuit voltage, 0.56 of filling factor, 1.17 of overall conversion efficiency.
