Roles of terminal groups of oligomer electrolytes in determining photovoltaic performances of dye-sensitized solar cells

Abstract

The effect of terminal groups of oligomer electrolytes on the photovoltaic performance of dye-sensitized solar cells (DSSCs) have been systematically investigated to show that the terminal group plays a critical role in determining the concentration of I-3(-), ionic conductivity, flatband potential and consequently the energy conversion efficiency.
