Abstract
This study examined the synthesis of the crystal structure of bis(2,2'-bipyridine)nitrato zinc (II) nitrate, [Zn(bipy)(2) (NO(3))](+)NO(3)(-) using a microwave treatment at 300 W and 60 Hz for the application to dye-sensitized solar cells. The simulated complex structure of the complex was optimized with the density functional theory calculations for the UV-vis spectrum of the ground state using Gaussian 03 at the B3LYP/LANL2DZ level. The structure of the acquired complex was expected a penta-coordination with four nitrogen atoms of bipyridine and the oxygen bond of the NO(3)(-) ion. The reflectance UV-vis absorption spectra exhibited two absorptions (L-L transfers) that were assigned to the transfers from the ligand (sigma, pi) of NO(3) to the ligand (sigma*, pi*) of pyridine at around 200 - 350 nm, and from the non-bonding orbital (n) of O in NO(3) to the p-orbital of pyridine at around 450 - 550 nm, respectively. The photoelectric efficiency was approximately 0.397% in the dye-sensitized solar cells with the nanometer-sized TiO(2) at an open-circuit voltage (Voc) of 0.39 V, a short-circuit current density (Jsc) of 1.79 mA/cm(2), and an incident light intensity of 100 mW/cm(2).
