A comparative study of ZnO, CuO and a binary mixture of ZnO0.5-CuO0.5with nano-dye on the efficiency of the dye-sensitized solar cell

Abstract

In this study, ZnO, CuO, and ZnO-CuO nanostructure with ZnO: CuO molar ratios of 1:1M, have been successfully synthesized via photolysis method. The synthesized nanostructure was designed to explore its morphology, structure and pureness. The XRD analysis confirmed that the synthesized particles are within the range of nanometers with their average particle size of below 100 nm, with SEM images showing the shape of the nanostructure. The purety of oxides was confirmed by the EDX analysis. Furthermore, the effect of adding nano dye on the performance of Dye sensitizes solar cells. Results showed that the added nano dye as A novel Nano copper complex as Bis [4-[(5-acetyl-2-aminophenyl) diazenyl]-1,5-dimethyl-2-phenyl-1H-pyrazole-3 (2H)-one] copper (II). In order to increase the surface grittiness of the active layer, hydrate improved absorption in the visible region. The power conversion efficiency (PCE), which was caused by an increase in Voc, Jsc and FF of the manufactured device, was improved through the inclusion of inorganic Dye.
