Özet

It is shown that the derivatives of 4,5-diazafluorenone-9-hydrazone containing thiophene and aldehyde anchor groups, as well as mixed-ligand Ru(II) complexes with these dyes and bipyridine, have the properties of sensibilizers of TiO2-based photovoltaic cells. The power conversion efficiency (η) in such photovoltaic elements under simulated 100 mW/cm2 solar radiation is in the range of 0.25-0.48%. The value of η in the case of compounds, bearing thiophene-2,5-dicarbaldehyde fragment as an anchor, is almost two times higher compared to the analogues, containing non-substituted thiophene fragment.
