AbstractIn this research, a series of Ru(II) complexes, ([Ru(1-7)(ina)(NCS)2] (1-7=5-[6-(5-mercapto-1,3,4-oxadiazol-2-yl)pyridin- 2-yl]-1,3,4-oxadiazole-2-thiol’s, ina=isonicotinic acid) were synthesized and characterized using different spectroscopic and analytic techniques, such as NMR, UV, IR, CV and CHN. Also, the new complexes were used in dye-sensitized solar cells (DSSC) as sensitizers. Current-voltage characteristics showed that the modifications of ligands clearly affected DSSC yield. Additionally, DFT calculations were performed and showed locations of frontier molecular orbitals of the complexes. While the locations of HOMO and HOMO – 1 orbitals are on Ru(II) metal center and SCN− ligands, the location of LUMO and LUMO + 1 orbitals are on the 1-7 ligands.

A dye-sensitized TiO2 thin film photoanode and carbon-based counter elctrode were fabricated on the FTO substrate with doctor-blade method. And we have coated the ZnO nanoparticles successfully on the TiO2 photoanode through a simple dipping treatment. The photoelectric performance of the assembled cells was investigated by absorption spectra and current-voltage characteristics (I-V curves). Results show that the absorbance of ZnO/TiO2 composite photoanode increases 5.4% compared to pure TiO2 photoanode. The optimal photoelectronic property can be reached when dipping time is 2h in Zn (CH3COO)2 solution. And at this point, the photoelectric conversion efficiency increases up to 50%. The enhancement mechanism has been discussed in detail.

A series of Zn–porphyrin dyes with different donor and π-linker groups based on the dye SM315 were systematically investigated to screen highly efficient candidates based on density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations.
