Huaqiao University Reports Findings in Nanosheets

February 19, 2014



By a News Reporter-Staff News Editor at Biotech Week -- Data detailed on Nanosheets have been presented. According to news reporting out of Xiamen, People's Republic of China, by NewsRx editors, research stated, "This paper reports a simple one-step hydrothermal route for the preparation of hierarchical nanosheets-based ZnO microstructures and their application to dye-sensitized solar cells. The morphologies of the products were controlled by the dosage of the reactants."

Our news journalists obtained a quote from the research from Huaqiao University, "Their physical characteristics were detected by X-ray diffraction, a field-emission scanning electron microscope and a surface analyzer. It is proved that the sample of ZnO microspheres with larger surface area and stronger light-trapping capacity since the superiority of their entirely spherical structures exhibits better photoelectrochemical properties than the mixtures of ZnO microspheres and ZnO microflowers."

According to the news editors, the research concluded: "A dye-sensitized solar cell assembled by the ZnO microspheres as photoanode shows an energy conversion efficiency of 2.94% after surface modification by tetrabutyl titanate solution at 90 degrees C. This result is over 1.6 times higher than the non-modified cell fabricated by the ZnO microspheres on the basis of the external improvement and the stability enhancement for the dye-sensitized ZnO photoanode."
