Comparative studies of pyridine and bipyridine ruthenium dye complexes with different side groups as sensitizers in sol-gel quasi-solid-state dye sensitized solar cells

Transparent quasi-solid state dye-sensitized solar cells sensitized with naturally derived pigment extracted from red seaweed

“…The calculated electron lifetime, also presented in Table 2, was 5.89 ms which is comparable even with electron lifetimes of newly synthesized ruthenium dye complexes [26].…”

Influence of Ancillary Ligands in Dye-Sensitized Solar Cells

“…89,80 The obtained results illustrated that branching of the side groups had no important effect on the absorption and electrochemical properties. 80 By the surface photovoltage (SPV) method, it was demonstrated that the strong influence of oxygen-containing side groups on the modulated SPV amplitude of the dye sensitized the ultrathin nanoporous TiO 2 layers in a gas atmosphere. Thus, different states may have appeared on the TiO 2 surface via the coordination of oxygen from the -C−O−C-groups.…”

“…Furthermore, the same research group synthesized new heteroleptic Ru­(II) dyes ( 20 – 23 ) with bpy and pyridine ligands along with amphiphilic structures substituted with these ligands. The influence of these ancillary ligands on electron back-transfer into the adsorbed Ru-dye molecules on the TiO 2 surface was investigated. , The obtained results illustrated that branching of the side groups had no important effect on the absorption and electrochemical properties . By the surface photovoltage (SPV) method, it was demonstrated that the strong influence of oxygen-containing side groups on the modulated SPV amplitude of the dye sensitized the ultrathin nanoporous TiO 2 layers in a gas atmosphere.…”

“…The effect of dissymmetry was also applied to the branched alkyl bipyridine ligands of ruthenium complexes (dye 5) when a study found that different branched groups did not impose an important effect on the spectroscopic and electrochemical properties. However, a sensitizer with highly conjugated dissymmetric alkyl bipyridyl ruthenium complexes gives rise to higher efficiency compared to those with low conjugated or symmetric ligands [14].…”
