Iranian Researchers Develop Convenient Method for Synthesis of Zinc Oxide Nanoflowers

TEHRAN (FNA)- Iranian researchers at the University of Kashan and Razi University managed to synthesize zinc oxide nanoflowers and apply them in improving the efficiency of conventional dye-synthesized solar cells to a great deal.



Thanks to the one-dimensional structure of the nanoflowers, the research team, led by Dr. Massoud Salavati Niasari, foresees other potential applications for the yielded product as well, such as in chemical sensors and light emitting devices.

To be more specific, the mentioned researchers employed a straightforward microwave-assisted method to produce ZnO nanoflowers and utilize them to make more efficient dye-synthesized solar cells which appear to be competitive to their counterparts available in the market.

In fact, the prepared nanoflower structure is comprised of hundreds of one-dimensional petals which serve as pathways to facilitate and enhance the electrons transfer occurring within the semiconducting zinc oxide wafer of the solar cell.

Achieving different morphologies and product phases by only changing the involved precursors as well as introducing a fast and cost-efficient zinc oxide nanoflowers synthesis method which hold promise for improving the performance of dye-synthesized solar cells are two major features of novelty for this research work.

The technical results pertaining to this experimental study are fully published in Chemical Engineering Journal.
