A Facile Novel Sonochemical-Assistance Synthesis of NiSe2 Quantum Dots to Improve the Efficiency of Dye-Sensitized Solar Cells

In this work, NiSe 2 quantum dot (QD) has been successfully synthesized from the reaction of SeCl 4 with pomegranate marc peels (PMP) dyes-Ni as a novel nickel precursor in the presence of potassium borohydride (KBH 4 ) through a simple and novel sonochemical-assistance route. In this work for preparing of nickel precursor and dye solar cells, the PMP was used because the PMP has several dyes such as proanthocyanidins and flavonoids that can easily be extracted by using ions. Besides, a possible reaction mechanism of the NiSe 2 -QDs has been discussed. Furthermore, for investigation the effect of different dyes and QDs on the solar cell yield, several experiments have been performed.
