Paper Abstract

In this paper we report on an attempt to substitute the liquid-electrolyte in Dye Sensitized Solar Cells (LC) by quasi-solid-state constructions (SC) adopting organic/inorganic gels as well as a novel dye comprised of a conjugated polymer covalently linked to a ruthenium complex that can be bound to a TiO2 anatase electrode. Gel polymer electrolytes are prepared by incorporating liquid electrolytes into a polymer matrix such as poly methyl methacrylate (PMMA) using a gelling solvent such as propylene carbonate (PC). Dye Sensitized Solar Cell (DSSC) fabricated using the former gel electrolytes and standard sensitizing dye such as cis-bis(thiocyano) ruthenium(II)-bis-2,2'-bipyridine-4,4'-dicarboxylate (N3) exhibit an encouraging short circuit current densitie (Jsc) of 4.45 mA cm-2 with open circuit voltages (Voc) of 495 mV. In the novel dye the conjugated polymer provides light harvesting and hole conduction while the ruthenium complex binds to the anatase electrode providing efficient charge carrier separation and injection into the anatase electrode.
