By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Biological Factors are presented in a new report. According to news originating from Islamabad, Pakistan, by NewsRx correspondents, research stated, "This work presents the chemical modification of ZnO nanorods with a sulphonic acid functionalized porphyrin derivative. The interaction between semiconducting nanorods and the porphyrin through sulphonic groups proved enough effective that the free base porphyrin behaved as metallated porphyrin under the grafted conditions which is a better donor than its free base counterpart."
Our news journalists obtained a quote from the research from Quaid-I-Azam University, "The soret band of grafted dye was red-shifted by 08 nm with respect to the reference. Additionally, two out of the four Q-bands of reference dye were found missing in the post grafting UV-Visible Spectrum. Fluorescence spectra of the dye before and after grafting were found completely different from each other supporting the UV-visible data. These modified ZnO nanorods in combination with P3HT were employed in the hybrid solar cells. The cells gave better efficiencies at low concentrations of the dye than the corresponding reference device consisting of ZnO nanorods and P3HT."
According to the news editors, the research concluded: "At high concentration of the dye the efficiency of the device was decreased."
