Stability Modification of Dye-sensitized Solar Cells by Ruthenium Dyes Embedded on Eggshell Membranes.

ABSTRACT: Dye-sensitized solar cells (DSSCs) have been one of the most promising technologies to convert sunlight into electricity repeatedly based on the mechanism that dyes inject/accept electron into the metal oxides/from redox mediator. Specifically, N719 ([RuL₂(NCS)₂], L: 4,4'-dicarboxy-2,2'-bipyridine), immobilized on TiO₂ through the interaction between its ligands (-COO^- and -NCS) and the oxygen on the TiO₂ surface, has been used as a conventional DSSC dye with high voltage. Nevertheless, -NCS ligands have been removed from Ru²⁺ in N719 due to UV irradiation and exchanged with H₂O or OH^- in electrolyte, resulting in voltage drop. In this work, we developed the first DSSC using the N719-adsorbed Eggshell (
