The influence of alkylpyridine additives to an I–/I3– redox electrolyte in MeCN on the performance of a bis(Bu4N)cis-bis(thiocyanato)bis(2,2′-bipyridine-4-carboxylic acid, 4′-carboxylate)ruthenium(II) dye-sensitized TiO2 solar cell was studied. I-V measurements were performed using >30 different alkylpyridines. The alkylpyridine additive had a significant influence on the performance of the cell. All the additives decreased the short-circuit photocurrent (Jsc), but most of the alkylpyridines increased the open-circuit photovoltage (Voc) and fill factor (ff) of the solar cell. The results of MO calculations suggest that the dipole moment of the alkylpyridine mols. correlate with the Jsc of the cell. The size and ionization energy of the pyridines also correlate with the Voc of a cell. Under AM 1.5 (100 mW/cm2), the highest solar energy conversion efficiency (η) of 7.6% was achieved by using 2-propylpyridine as an additive, which was more effective than the previously reported additive, 4-t-butylpyridine. In the experiment, the researchers used many compounds, for example, 2-Isopropylpyridine (cas: 644-98-4Related Products of 644-98-4).
2-Isopropylpyridine (cas: 644-98-4) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Related Products of 644-98-4
