A new cyanine dye, 7-{1-[2-(4-morpholine-1,8-naphthalimide)ethyl]-1H-1,2,3-triazol-4-}-2-[3-(5-carboxyl-1,3-dihydro-3-3-dimethyl-1-butyl-indolin-2-methylene)-propenyl]-1,1-dimethyl-3-buty-1H-benzo[e]indolium iodide (BIDC), has been synthesized and identified with regard to its structure and photoelectrochemical properties used as a sensitizer on dye-sensitized solar cells. A novel solid-state electrolyte with polyaniline-loaded carbon black (PACB)-1-methyl-3-propylimidazolium iodide (MPII) composite was investigated on these dye-sensitized solar cells (DSCs). The shortcircuit photocurrent density (J(sc)), open-circuit photovoltage (V-oc) and fill factor (ff) under 200 W/m(2) white light from a xenon lamp are 0.44 mA/cm(2), 550 mV and 0.58, respectively, yielding an overall conversion efficiency (eta) of 0.7%. The most merit of the solid-sate electrolyte was free of volatile and flammable fluid components and easy of encapsulation for DSCs.
