doi:10.7517/j.issn.1674-0475.2007.06.422

Abstract

Abstract: 1-Butyl-3-methylimidazolium iodide was synthesized by quaternization.The photovoltaic performance of dye-sensitized solar cells (DSCs) was compared for electrolytes containing different concentrations of I,KI and iodine.After optizimed,the DSCs with the electrolyte (0.90 mol·L^-1 I,0.50 mol·L^-1 KI and 0.12 mol·L^-1 I₂ in GBL) gave short circuit photocurrent density (J_sc) of 15.97 mA·cm^-2,open circuit voltage (V_oc) of 0.71 V,and fill factor (FF) of 0.55,corresponding with the photoelectric conversion efficiency (η) of 6.34% under one Sun (Xenon lamp,AM1.5,100 mW·cm^-2).

Key words: ionic liquid, 1-butyl-3-methylimidazolium iodide, dye-sensitized, solar cell
