Related Products of 1671-88-1. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine, is researched, Molecular C12H10N6, CAS is 1671-88-1, about Influence of aminotriazole additives in electrolytic solution on dye-sensitized solar cell performance.

The influence of aminotriazole additives in acetonitrile solution of an I-/I3- redox electrolyte on the performance of a bis(tetrabutylammonium)cis-bis(thiocyanato)bis(2,2′-bipyridine-4-carboxylic acid, 4′-carboxylate)ruthenium(II) (N719) dye-sensitized TiO2 solar cell was studied. The current-voltage characteristics were investigated under AM 1.5 (100 mW/cm2) for 10 different aminotriazole compounds The aminotriazole additives tested had varying effects on the solar cell performance. Most of the additives enhanced the open-circuit photovoltage (Voc), fill factor (ff) and the solar energy conversion efficiency (η), but reduced the short circuit photocurrent d. (Jsc) of the solar cell. The highest η of 7.6% was obtained by adding 3-amino-1H-1,2,4-triazole and η was comparable to that of 4-t-butylpyridine (TBP). Both the phys. and chem. properties of the aminotriazoles were computationally calculated in order to determine the reasons why the additive affects the solar cell performance. The greater the calculated partial charge of the nitrogen atoms in the mol., the larger the Voc value. The Voc of the solar cell also increased as the size of the aminotriazole mols. decreased. The Jsc value increased with increasing the absolute difference in the dipole moments between the calculated aminotriazoles and acetonitrile. These results suggest that the electron donicity of the aminotriazole additives influenced the interaction with the TiO2 photoelectrode and the solvent, which altered the dye-sensitized solar cell performance.
