Photovoltaic Properties of Dye-Sensitized Solar Cells using Metallophthalocyanines with Poly(ethylene glycol) Electrolytes

Dye-sensitized solar cells (DSSCs) were prepared with a poly(ethylene glycol) (PEG) electrolyte using various metallophthalocyanines (MPcs) as an additive. The DSSC device using MPcs has higher power conversion efficiency than that without MPcs, due to decrease of electron transfer distance by the interface adsorption between TiO2 film and PEG electrolyte. The best result on power conversion efficiency was 4.18% in DSSC device using InOHPc. The open-circuit voltage (V-oc) was 0.70V, the short-circuit current density (J(sc)) was 10.20mA/cm(2), and the Fill Factor (FF) was 0.58. The addition of MPcs as an additive is useful to improve the performances of DSSC devices such as V-oc, J(sc), and power conversion efficiency.
