“Background Dye-sensitized solar cells (DSSCs) have attracted considerable attention as a viable alternative to conventional silicon-based photovoltaic cells  because of their Suplatast tosilate low-production cost, high conversion efficiency, environmental friendliness, and easy fabrication procedure [2–5]. A typical DSSC is comprised of a nanocrystalline semiconductor (TiO2), an electrolyte with redox couple (I3 −/I−), and a counter electrode (CE) to collect the electrons and catalyze the redox couple regeneration . Extensive researches have been conducted in order for each component to achieve highly efficient DSSCs with a modified TiO2, alternative materials [8, 9], and various structures [10–12]. Usually, Pt-coated fluorine-doped tin oxide (FTO) is used as a counter electrode owing to its superior catalytic activity . However, there are researches reporting that Pt corrodes in an electrolyte containing iodide to generate PtI4[14, 15].
