Abstract
This work is focussed on increasing optical transmittance of ZnO nano powders by doping it with CuO and phycocyanin. ZnO –CuO nanocomposites were prepared by sol gel assisted methods with Zinc acetate and Copper chloride as precursors. The prepared nanocomposites were characterised by X-ray diffraction (XRD) for structural features and Scanning Electron microscope (SEM) for morphology. The crystallite size from XRD pattern was found to be 24 nm. Phycocyanin was incorporated in the prepared ZnO-CuO nano powders by hand milling technique and optical absorption was analyzed with UV-Vis spectroscopy studies. The absorbance of phycocyanin included ZnO-CuO nanocomposites was decreased in the range of 550-750 nm compared to pure ZnO-CuO nanocomposites indicating a rise in transmission. This is a successful attempt to increase the transmission from 500 nm for ZnO based solar cells against the previously reported low transmittance in visible range. The work recommends incorporation of Phycocyanin for cheap efficient higher transmission nanostructures- based metal oxide solar cells.
